Question 6

What will be the resistance of a wire across which, when 2V potential difference is applied, 1A current flows through the wire?

Solution

Given that :-

Potential Difference => 2v

Current => 1 Ampere

=> Resistance R = ?

Using Ohm's Law ,

Potential Difference ( V ) = Current ( I ) × Resistance ( R )

=> 2 = 1 × R

Resistance = 2 Ohms.
