Question

When a 12 v battery connected across an unknown resistor, there is a current of 2.5ma in a circuit.Find the value of the resistance of the resistor?

Answer 1

Explanation:

V=12V

I=2.5 mA

=2.5×10^-3 A

R=V/I

=12/2.5×10^-3

=4.8×10^3

=4800 ohm

Answer 2

Answer:

R=V/I

R=12/2.5

=4.8 ohm
