Question

when a 9 volt battery is connected across an unknown resistor there is a current of 3A in a circuit. find the value of resistance in the circuit? ​

Answer 1

By Ohm's law

V=IR

So, R= V÷I

Substituting the given values we get,
R= 9÷3= 3 ohms

According to Ohm’s law,

V = IR

=v/I

Here, V = 9V and I = 3 A

Therefore,

=9/ 3 =3 Ω

I hope, this will help you___❤❤
