Question

when a 12 volt battery is connected across an unknown resistor there is a current of 2.5 m a in the circuit find the value of the resistance of the resistor​

Answer 1

Answer:

4.8 ohms

Explanation:

v = i  x R

= R = v / i

= 12 / 2.5

= 4.8 Ω

Answer 2

Answer:

R=V/I

R=12/2.5

=4.8 ohm
