Question

If a sine wave has an RMS voltage of 20 volts, what will be its Peak voltage?

A. 28.3 V
B. 10 V
C. 22.1 V
D. 36.5 V

Answer 1

The peak voltage of a sine wave with an RMS voltage of 20 volts is approximately 28.28 V, which is closest to 28.3 V, option A.

Step-by-step explanation:

If a sine wave has an RMS voltage of 20 volts, the Peak voltage can be calculated using the formula Vo = √2 * Vrms. To find the peak voltage, you multiply the RMS voltage by the square root of 2 (approximately 1.414). Therefore, using the given RMS voltage of 20 volts:

Vo = 1.414 * 20 V = 28.28 V

So, the closest answer to 28.28 V would be A. 28.3 V.
