Question

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.​

Answer 1

Explanation:

let that resistor resistance be x

v=ir

2.5mA= 2.5X10^-3

12=i X 2.5X10^-3

12/2.5X10^-3= i

12000/2.5= i

120000/25= i

4800ohm=i
