Question

half cycle time duration for 50Hz frequency

Answer 1

Answer:

no it is wrong question

Answer 2

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.
