A periodic voltage having the Fourier series V(t) = 1 + 4 sin ωt + 2cos ωt volts is applied across a one-ohm resistor. The power dissipated in 1-ohm resistor is—
-
- 1W
- 11W
- 21W
- 24.5W
Correct Option: B
Vrms of the given Fourier series
= √1 + 4².½ + 2². ½
= √11
Power dissipated in 1 – Ω resistor
= | = | = 11watt | ||
