Question

an electric lamp of 100 Ohm a toaster of resistance 50 ohms and a water filter of resistance 500 ohm are connected in parallel to a 220 voltage source what is the total resistance and the current through it ​

Answer 1

1/Req=1/100+1/50+1/500

=(5+10+1)/500

=16/500

Req=500/16

I=V/R

=(220*16)/500

I=7.04A
