Question

when a 4V battery is connected across an unknown resistor there is a current of 100mA in the circuy.The value of the resistance of the resister is​

Answer 1

Answer:

given

V= 4v

I = 100 x 10^-3 A = 10A

resistance = V/I = 4/10 = 0.4ohm

hope this will help you..

Answer 2

Answer:

v=iR

R=v/i

v=4 volts

i=100^-3 A

therefore. R=40ohm
