The peak value `A.C` is `2 sqrt(2)A`. It's apparent value will be

The peak value of 220 a.c. is

The peak value of AC mains (in volt) is

Assertion : An electric bulb is first connected to a dc source and then to a ac source having the same brightness in both the cases. Reason : The peak value of voltage for an A.C. source is sqrt(2) times the root mean square voltage.

In a common emitter configuration, a transistor has beta=50 and input resistance 1kOmega . If the peak value of a.c. input is 0.01 V then the peak value of collector current is

The peak vlaue of alternating current is 5sqrt(2) . The mean square value fo current will be

In an A.C. circuit the peak value of voltage is 424V. Its effective voltage is

If the r.m.s. value of A.C. is I_("rms") then peak to peak value is –
