Question 1

When a resistance is connected across the terminals of a 120 V rms 60 Hz AC source, the rms current which flows through the circuit is I1. If the rms voltage of the AC source is kept constant and the frequency is increased to 120 Hz, the rms current flowing through the circuit is I2. The ratio of I1 to I2 is:

• A. 1/4
• B. 1/2
• C. 1
• D. 2
• E. 4
