The r.m.s value of an a.c of `59 Hz` is `10 A`. The time taken by the alternating current in reaching from zero to maximum valuef and the peak value of current will beA. `2 xx 10^(-2) "sec"` and `14.14 A`B. `1 xx 10^(-2) "sec"` and `7.07 A`C. `5 xx 10^(-3) "sec"` and `7.07 A`D. `5 xx 10^(-3) "sec"` and `14.14 A` |
Answer» Correct Answer - 4 `i_(0) = sqrt(2) i_("rms")` , `T = (1)/(f), t = (T)/(4)` |
