Question

Частота колебаний в сети переменного тока 50гц. найти период колебаний?

Answer 1

v=50    T=?

v=1/T    T=1/v=1/50=0.02 c

Answer 2

Frequency of AC Power Supply

The frequency of the alternating current (AC) power supply is 50Hz.

Calculating the Period of Oscillation

To find the period of oscillation (T) for a frequency (f), the formula T = 1 / f is used. Therefore, for a frequency of 50Hz, the period of oscillation can be calculated as: T = 1 / 50.

So, the period of oscillation for a 50Hz AC power supply is 0.02 seconds.
