Hello, could anyone have a quick look and check if i have done it right .
Thank you
I=P/V=500/120=4.16A
Z=V/I=240/0.5=480 Ohms
Rlamp=V/I=120/5=60 Ohms
480^2-60^2=476 Ohms after rooting
Xc=1/2pie*f*C
1/2pie*50*476=6.6uF
Q
A metal-filament lamp is rated at 120V, 500W. It is to be connected in series with a capacitor to a power supply of 240V 50Hz
