Question

When 2V is the potential difference across a conductor the current in the conductor is 0.4 ampere. What is the resistance of the conductor?

Answer 1

Step1:- Given data:

Potential difference is $V=2V$

Current in the conductor is $I=0.4ampere$

Step2:- Finding the resistance of the conductor

According to ohm's law

$V=IR$

$\Rightarrow R=\frac{V}{I}=\frac{2}{0.4}=5ohm$

Hence, the resistance of a conductor is 5 ohms.
