Question

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


BEST ANSWERER WILL BE MARKED BRAINLIEST​

Answer 1

Answer:

We have potential difference (V) = 12V

Electric current (I)=2.5 mA= 2.4×10-3

According to Ohm’s Law (V) = IR

Or R = V/I
