Question

When a 12 volt battery is connected across a unknown resistor there is a current of 2.5 milliamphere in the in the circuit find the value of the resistance of the system?

Answer 1

the answer is 4800 ohms . formula used was v = I × r.

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
