When a 12 V battery is connected across ...

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

Text Solution

Verified by Experts

V=12 V
I=2.5 mA = `2.5xx10^(-3)` A
R = ?
`R= (V)/(I) = (12)/(2.5xx10^(-3))`
=` 4800 Omega`
