A potential difference of 5" " V when applied across a conductor produces a current of 2.5" " mA. The resistance of the concictor (in Ω ) is:

Correct option is C

Sol: the correct answer is (c) 2000

Given:

V = 5V

I = 2.5mA = $$\frac{2.5}{1000}$$ = 0.0025 A

Formula used:

Ohm's law V= IR

Solution:

To find Resistance

V= IR

5= 0.0025 x R

​$$\frac{5}{0.0025}$$ = R

R= 2000Ω

Resistance is 2000Ω
