Question 5: If the peak values of a sine wave is 1000 volts, what is the effective value (Eff)?


The sine wave of an alternating voltage is given by V = Vmsinωt. Here V is the instantaneous voltage, Vm is the maximum voltage during the period and ω is the angular velocity of the voltage.

The effective value of such a voltage is given by Vrms. We know that

In the given problem, Vm = 1000 V. Put this value in the above equation.
