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

Step-by-step explanation:

1 mA = 1/1000A

2.5mA = 2.5*1/1000

= 0.0025A

V =IR

12 = 0.0025*R

12* 10000/25 = R

12* 400=R

4800 ohm =R

therefore the resistance Of The resistor is 4800 ohms

Answer 2

Step-by-step explanation:

therefore the resistance of the resistor is 4800 ohms
