Question

When a 12V battery is connected across an unknown resistor, there is a current of 2.5mA in the circuit. Calculate the value of resistance of the conductor.

Answer 1

V = ir
12=2.5ma*r
r = 12/2.5*1000=12000/2.5=4800ohm

According to Ohm’s law,

V = IR

=v/I

Here, V = 12 V and I = 2.5 mA = 0.0025 A Therefore,

=12/ 0.0025 = 4800 Ω = 4.8 kΩ

I hope, this will help you___❤❤
