1.	If the rms current in a 50 Hz ac circuit is 5 A, the value of the current `1//300` second after its value becomes zero isA. `5 sqrt 2`AB. 5`sqrt 3/2 `AC. 5/6 AD. 5/`sqrt 2` A
Answer» Correct Answer - B Given, v = 50 Hz, `underset(rms)(I)` = 5 A `t = 1/300` s We have to find I(t) `underset(o)(I)` = Peak value = `sqrt 2underset(rms)(I)` = `sqrt 2 xx 5` = `5sqrt 2` A I = `underset(o)(I) sin omegat = 5sqrt 2sin 2pivt = 5sqrt 2sin 2pivt = 5sqrt 2sin 2pi xx 50 xx 1/300` `5sqrt 2 sin pi/3` = `5sqrt 2 xx sqrt 3 / 2` = `5sqrt 3/2` A
