An alternating current is given by the following equation: `I=3sqrt(2)sin (100 pi t+pi//4)`. Give the frequency and rms value of the current.

An alternative current in amperes us given by I=50 sin (400 pi t+phi) . Find the frequency and the rms value of the current

An alternating current is given by the equation i=i_(1)sin ω t+i_(2)cosω t .The rms current will be :

The equation of an alternating current is I = 20 sin 300 pi t . Calculate the frequency and r.m.s value of current.

The equation of an alternating current is I = 50 sqrt(2) sin 400 pi t A , then the frequency and the root mean square value of current are respectively.
