Q

# A 100 W resistor is connected to a 220 V , 50 Hz ac supply. What is the net power consumed over a full cycle?

Q7.1 (c) $100\Omega$ resistor is connected to a $220\: V$$50\: Hz$ ac supply.

What is the net power consumed over a full cycle?

Given,

Supplied RMS Voltage $V_{rms}=220V$

Supplied RMS Current$I_{rms}=2.2A$

The net power consumed over a full cycle:

$P=V_{rms}I_{rms}=220*2.2=484W$

Hence net power consumed is 484W.
