Question

The sinusoidal potential difference $V_1$ shown in figure applied across a resistor R produces heat at a rate W,What is the rate of heat dissipation when the square wave potential difference $V_2$ as shown in figure is applied across the resistor?

• A. $\frac{W}{2}$
• B. W
• C. $\sqrt{2}W$
• D. 2W

Answer 1

The correct option is A $\frac{W}{2}$

For $ac=w=$ heat at a rate

when it will be the, half of one cycle is omitted. Hence, $\frac{w}{2}$
