Question

When a 12v battery is connected across an unknown resistor, there is a current of 2.5 m a in the circuit. find the value of resistance of the resistor?

Answer 1

Hey friend
here is your answer

voltage (v) = 12 V
current (I) = 2.5 A

resistance(r) = ? ( to find )
as,

V = I × r
12 =2.5 × r
r = 4.8 ohm

therefore the resistance offered by the circuit be 4.8 ohm


glad to help you
hope it helps
thank you.

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
