Question

When a 12 V battery is connected across an unknown resistor, there is a current of 2.5 mA in the circuit. Calculate the value of the resistance of the resistor.

Answer 1

Answer:

4800 Ohm

Explanation:

V = 12 v

I = 0.0025 A

R = ?

R = V / I

R = 12 / 0.0025

R = 4800 ohm

Answer 2

Answer:

R=V/I

R=12/2.5

=4.8 ohm
