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=12V,I=2.5mA=2.5xx1^(-3)A`
`R=V/I=(12V)/(2.5xx10^(-3))=4.8xx10^(3)Omega`
