Question

In a 12 volt battery, it is connected across an unknown resistor, their is a current of 2.5 miliampere in the circuit. find the value of the resistance of the resistor

Answer 1

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
R = 12/2.5 *10^-3
R =4.8*10^3 ohm

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___❤❤

Thank you
