What is the average power dissipated by a resistor of resistance R = 25 in an LRC circuit for which the power factor is equal to 0.25 and the maximum voltage of the AC source is 8 V?

A)

0.04 W
B)

0.32 W
C)

0.16 W
D)

0.62 W
E)

0.08 W

Question 2

A voltage reading is obtained by placing a voltmeter across a resistor. What happens to the total current flowing in the circuit as a result of this action?

A)

The current increases.
B)

The current decreases.
C)

The current does not change.
D)

The current increases if the meter's internal resistance is less than the original resistance in the circuit and decreases if its internal resistance is greater than the circuit's original resistance.
