Electric shock | Electrical Engineering homework help


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…).
