If a circuit has 15 cycles per 1/4 second, what is its frequency in Hertz?

Explanation:
Frequency in Hertz is the number of cycles per second. Here you have 15 cycles in 1/4 of a second. Since one second contains four such quarter-second intervals, the number of cycles in one second is 15 × 4 = 60. Therefore the frequency is 60 Hz. (Equivalent check: 15 ÷ 0.25 = 60.)
