Question

when a 4v battery is connected across an unkown resistor there is a current of 100mA in the circuit.The value of the resistance of the resistor is:​

Answer 1

Answer:

V = I R

R = V/I

R = 4/10^-1

R = 40ohm

Thanks for Reading

Answer 2

Answer:

v=iR

R=v/i

v=4 volts

i=100^-3 A

therefore. R=40ohm
