Test Preparation on Electrical And Electronics Test Preparations On Series Circuits Part 2

1.

When a fourth resistor is connected in series with three resistors, the total resistance

1increases by one-fourth
2increases
3decreases
4remains the same

2.

A string of five series resistors is connected across a 6 V battery. Zero voltage is measured across all resistors except R3. The voltage across R3 is

10 V
21.2 V
36 V
40.6 V

3.

When one of three series resistors is removed from a circuit and the circuit is reconnected, the current

1increases
2increases by one-third
3decreases by one-third
4decreases by the amount of current through the removed resistor

4.
