The instantaneous current from an a.c source is `I = 5 sin 100 pi t` What is the frequency of a.c. ? What is the rms value of current ? |

Answer» Here, `I = 5 sin 100 pi t` Compare with `I = I_(0) sin omega t` ` I_(0) = 5 A, omega = 2 pi v = 100 pi`, `v = (100)/(2 pi) = 50 Hz` `I_(v) = (I_(0))/(sqrt 2) = (5)/(sqrt 2) = (5 sqrt 2)/(2) = 3.54 A` |
