1. If a +3(C) charge moves through a circuit element and in so doing the charge looses 12(J) of energy, then what is the magnitude of the voltage across this circuit element?

A) 3(V)
B) 4(V)
C) 12(V)
D) 36(V)

2. For the same circuit element and situation described in question 1, is the +3(C) of charge passing through a voltage rise or a voltage drop?
A) voltage rise
B) voltage drop

3. An electrical energy source forces a constant current of 500(mA) through a light bulb for one hour. If 12.6(kJ) is given off in the form of light and heat energy, calculate the voltage drop across the bulb.Use Engineering Notation with 3 decimal point accuracy
