Question

A potential difference of 10v appears across the ends of a resistor when 5a of current flows through it find resistance of the resistor

Answer 1

V =10v
I=5A
R=?
R=V/I
R=10/5 =2ohm

Answer 2

Answer:

The resistance of the resistor is 2Ω

Explanation:

The potential difference across the ends of the resistor is V=10 V

The current flows through the resistor is I=5 A

According to ohm's law

We know that potential difference across a resistor is equal to the product of current and the resistance of the resistor R.

$V=IR\\R=\dfrac{V}{I}\\R=\dfrac{10}{5}\\R=2Ω$
