Answer:
if frequency is 50Hz
Explanation:
we know that time period for 1 Oscillation is 1/50sec .
but in one cycle direction changes twice so, every half time period polority is reversed ,so every 1/ th second which implies that in one second direction changes times

Answer:
If frequency is 50Hz, we know that time period for one full "oscillation" or AC wave, is 1/50 sec, But in one cycle, direction changes twice. So, every half time period, polarity is reversed, so every 1/100th sec. Which implies that, in 1 sec, direction changes 100 times
