Question

AC or electrical hum generally occurs at what frequency?

a) 50 Hz
b) 60 Hz
c) 70 Hz
d) 80 Hz

Answer 1

AC or electrical hum generally occurs at 60 Hz in the United States and 50 Hz in many other countries, depending on the standard frequency for AC power.

Step-by-step explanation:

AC or electrical hum generally occurs at a specific frequency depending on the country's electrical power transmission standard. In the Unites States, the standard frequency for AC power is 60 Hz, while in many other countries, such as those in Europe, the standard frequency is 50 Hz. These frequencies are foundational for the operation of AC electrical appliances and are directly related to the characteristic hum that can sometimes be heard emanating from electrical devices.
