The r.m.s. value of an alternating current is

The ratio of peak value and r.m.s. value of an alternating current is

The r.m.s.value of an alternating current of 50 Hz frequency is 10A.The time taken by the A.C.current in reading from zero to maximum value and the peak value of current will be

What is the r.m.s. value of an alternating current which when passed through a resistor produces heat which is thrice of that produced by a direct current of 2 amperes in the same resistor?

What is the r.m.s. value of an alternating current which when passed through a resistor produces heat which is thrice of that produced by a direct current of 2 amperes in the same resistor?

The ratio of peak value and r.m.s value of an alternating current is

The rms value of an alternating current

The rms value of an alternating current

Assertion (A) : The r.m.s value of alternating current is defined as the square root of the average of I^(2) during a complete cycle. Reason (R ) : For sinusoidal a.c. (I = I_(0) sin wt) I_("rms") = (I_(0))/(sqrt(2))

Calculate the r.m.s. value of alternating current shown in the figure
