Which of the following statements is true when the lead of a test light or common lead of the voltmeter is connected to chassis ground?
A good fuse shows a very high resistance.
A blown fuse has 0 volts on one side of the fuse.
A good fuse has battery voltage on only one side of the fuse.
A blown fuse has the same voltage on both sides.
Calculate the voltage of a circuit that is rated as 1.5 amps and has a resistance of 2 ohms across it.
3 volts (V = I × R = 1.5 × 2)
0.75 volts (V = I × R = 0.5 × 1.5)
1.5 volts (V = I × R = 1.5 × 1)
2 volts (V = I × R = 2 × 1)
Select one:
3.5 V
0.5 V
3 V
0.75 V
