Question

Resister of 2ohm and 4ohm are connected in parallel with a battery of 10v calculate the total resistance and current through each resistor

Answer 1

Answer:

Total resistance 1/R=1/2+1/4

by solving R=4/3

V=10v

I=V/R

=10 divide by 4/3

=30/4

=7.5

Answer 2

Answer:

R1=20 ohm , R2=40 ohm V=E=10v total resistance R=(R1×R2)/R1+R2 R=(20×40)/(20+40) R=80/60 =4/3 ohm =1.33 ohm total current I=V/R=E/R=10/(4/3) I=15/2=7.5 Amp
