Question

question 3
with a 60 hertz (hz) power source, alternating current changes the direction of current flow 60 times per second.
a true
b false
clear selection

Explanation:

The frequency of an alternating current (AC) is defined as the number of complete cycles per second. One cycle of AC involves the current changing direction twice (from positive to negative and back to positive). So, if the frequency is 60 Hz (60 cycles per second), the current changes direction \(2\times60 = 120\) times per second.

Answer:

B. False
