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) A`B. `5 sqrt((3)/(2))A`C. `(5)/(6) A`D. `(5)/(sqrt(2))A`
Answer» Correct Answer - 2 Here, `I_("rms") = 5 A, upsilon = 50 Hz, t = (1)/(300) s` `I_(0) = sqrt(2) I_("rms") = 5 sqrt(2) A`. From `I = I_(0) sin omega t = I_(0) sin 2 pi upsilon t` `I = 5 sqrt(2) sin (2 pi xx 50 xx (1)/(300))` `= 5 sqrt(2) "sin" (pi)/(3) = 5 sqrt(2) (sqrt(3))/(2) = 5 sqrt((3)/(2)) A`
