Give specific examples. 

 
Identify parts of the E-Cig that constitute voltage, current, and  resistance. Discuss the role each plays in the E-Cig and typical values  for each including units.
E-Cigs (or vapes) consist of a battery, typically lithium-ion, that  connects to a single or dual heating coil into the reservoir of vape  liquid. I’m going to use the specs for a vape that I’m currently using,  called the Elf Bar BC5000. It consists of a 650mAh (nominal voltage is  3.7 V) rechargeable lithium-ion battery, a dual coil, and a cotton  reservoir filled with 13ml of juice (nicotine salts). As a user hits or  pulls air from the mouthpiece, the airflow activates a sensor switch to  the battery and sends current through the circuit to the atomizer which  houses a coil(s). The coils offer resistance. The only resistance  information I could find for Elf Bar mesh coils is around 1.2 ????. The  lower the resistance, the more heat and vapor are produced, and the  stronger the hit. The higher the resistance, the less vapor and heat are  produced and smoother the hit. The coil(s) heats the “wick” which is  typically cotton inside of a reservoir filled with juice creating vapor  which expels through the mouthpiece. Using Ohm’s Law and assuming the  resistance is 1.2 ????, we can determine the current for this disposable  vape is 3.7V/1.2 ????=3.08333333A.
Discuss the electrical dangers of an E-Cig. Give specific examples. 
One of the primary electrical dangers associated with E-Cigs or vapes  are the batteries. The type of batteries used in these devices has been  unregulated. Lithium-ion batteries can be dangerous if they become  damaged or over-heated. The chemical within the battery reacts to oxygen  and can combust. If this happens while in use or carried by and  individual, serious injury can occur.
There are many electrical safety rules.  Pick one, and discuss its application on a small system, such as the E-Cig.
It is important to know the requirements for each specific device.  Due to the sensitive nature of lithium-ion batteries, it is important to  handle them with care. Use the correct charger that comes with the  device or charger specified. Be sure to charge away from flammable  materials and do not leave the device charging overnight or for extended  periods of time.

Identify parts of the E-Cig that constitute voltage,  current, and resistance. Discuss the role each plays in the E-Cig and  typical values for each including units.
In this section of our discussion, the components of the E-Cig and  their functions in relation to Ohm’s Law factor (i.e., current, voltage,  and resistance) will be summarized. The rechargeable battery is the  voltage source (sometimes called the electromotive force (EMF) that  causes electrons to flow (current) through the light and heater. The  example E-cig in figure 1 shows the two resistors (i.e., the heater and  light (LED) represented by 
and  Since the current divided equally by each resistor 
,  the voltage (4.2v) is the same across each resistor (parallel  resistors). The current leaving (1.909A) the battery is equal to the  current returning to the battery. The heater applies energy  (vaporization to the nicotine/liquid cartridge when the user inhales or  pulls on the E-cig. The integrate circuit (I.C. or microprocessor)  controls the heater and light. The microprocessor has an applied voltage  and current (although relatively small when compared to the other  components). The operation of the microprocessor is beyond the scope of  our present course/discussion
*Discuss the electrical dangers of an E-Cig. Give specific examples. 
E-cig accidents are most often caused by the rechargeable batteries.  Explosions can be caused by overcharging, incompatible chargers, and the  improper handling of carrying spares in the pocket with the terminals  exposed to other metal objects like car keys and coins. In 1991, the  relative new lithium-ion battery replaced the older lithium metal  battery which was very explosive.
The user should never use the E-cig while it is being charged. There  is a chance of too much current draw and overheating which could result  in damage to the E-cig circuit components and an electric shock to the  user. The subject of electric shock by such a small device might seem  unusual. To briefly explain the phenomena of electric shock, there is a  relatively small current necessary to cause electric shock in a human.  Here is a brief representation of values of current and their possible  effects on a human.
*.001A or 1ma (Threshold of Sensation)
*.01A or 10ma (Mild Sensation)
*.01A to 0.1A or 10ma to 100ma (Painful to Breathing difficulties)
*0.1A to 0.2A or 100ma to 200ma (Death)
*0.2A to 1A or 200ma to 1000ma (Breathing Stops, Severe Burns)
*There are many electrical safety rules.  Pick one, and discuss its application on a small system, such as the E-Cig.
One safety measure on a small system  such as an E-cigarette would be to always keep the terminals separated  and therefore prevent electrical shortages. One example of how ignoring  this preventative measure could be even more dangerous when applied to  an automotive system would be to allow a tool such as a long screwdriver  to come into contact with the positive and negative terminals of the  large battery (12-V) in an automobile. This “dead short” can produce a  high level of current (i.e., 600A, 400A, 300A, etc.) Even though this 12  V has relatively low voltage the cranking amps of the battery can be as  high as 800A. Consider the Power Formula (P=IV)       P= (800A) (12V) =  9,600watts or 9.6kw

However, there are also small circuits, such as the ones  you learn to design in this course, that are very dangerous.

 
Most people think of electrocution from overhead wires or dangerous  power lines. However, there are also small circuits, such as the ones  you learn to design in this course, that are very dangerous. One such  example is the electronic cigarette, or E-Cig for short (See Figure 1  below). This is actually a small systems engineering device designed to  be carried on your person. It consists of a small dc circuit with  voltage, current, and resistance (See Figure 2 below). We know that all  current, large and small, can have a dangerous impact on the human  body. 
In your original post, answer the following:
Identify  parts of the E-Cig that constitute voltage, current, and resistance.  Discuss the role each plays in the E-Cig and typical values for each  including units.
Discuss the electrical dangers of an E-Cig. Give specific examples. 
There are many electrical safety rules.  Pick one, and discuss its application on a small system, such as the E-Cig.
In your responses to your classmates  discuss how you would translate the safety rule your classmate chose to  a larger system (e.g. car, home, power plant, robot on factory  floor…).

While we are aware that the industrial growth of the United States at the end of

While we are aware that the industrial growth of the United States at the end of the Nineteenth and the beginning of the Twentieth Centuries led to the nation becoming an economic world superpower, it came at many costs.  These cost not only had an impact on the people back then, but continue impacting you today.  choose one of the costs of industrialization from the list below and describe its impact during the end of the Nineteenth and beginning of the Twentieth Century.  Then, analyze the continued effect of your chosen cost on the world you live in today.  Finally, evaluate attempts by the United States government to mitigate (lessen) the impact of the cost you have chosen.  Be sure to use evidence in your descriptions and in support of your evaluation.
Air pollution, Depletion of Natural Resources, Growing income inequality, water pollution, worsening working conditions.
