Question

Two resistors of resistance 4 ohm and 6 ohm are
connected in parallel to a cell to draw current 0.5 A
from the cell.
(a) Draw a labelled diagram of the arrangment.
(b) Calculate the current in each resistor.​

Answer 1

V=IR

1/Resistance in parallel = 1/4 +1/6

=5/12

Resistance in parallel= 12/5 ohm

V=12/5*0.5

V=1.2 v

=>Current in 4ohm resistor

I =V/R

=1.2/4

=0.3 A

=>Current in 6ohm resistor

I=V/R

=1.2/6

=0.2 A

Therefore, current in 4ohm resistor is 0.3A and 6ohm resistor is 0.2A
