| Q1: Which of the following equations correctly states Ohms Law?|
V = I * R
I = E / R
R = E / I
All of the above are correct.
| Q2: A series DC circuit has a 100 Ohm resistor. If the applied voltage is unchanged and another 100 Ohm resistor is placed in parallel with the first resistor what will happen to the circuit current?|
It will remain the same.
It will increase.
It will decrease.
None of the above since only the resistance has changed.

The resistance will increase
The resistance will decrease
The Inductance will decrease.
The inductance will increase.
| Q4: If the voltage applied across a 50 Ohm resistor is doubled and the current through the resistor doubles, what has happened to the resistor value? |
The resistor value decreased.
The resistor value increased.
The resistor value was unchanged.
None of the above is correct.
| Q5:If a voltage of 12 volts is applied across a resistor and the current is 5 amps what is the power dissipated by the resistor?|
