Question

When 12v battery is connected across as known resistor there is a current of 2.5MA in the circuit
Find the resistance of resistor? ​

Answer 1

Answer:

battery 12v

current 2.5 mA=2.5/1000A

so resistance

V=IR

R=V/I

R=12/(2.5/1000)

=12*1000/2.5

12*1000*10/25

12*400

4800ohm

Answer 2

Answer:

R=V/I

R=12/2.5

=4.8 ohm
