Question

A current of $0.5A$ flows through a conductor of resistance $5\Omega$. Calculate the potential difference at the ends of the conductor.

Answer 1

Step 1: Given data and formula

Given data:

1. Current flowing through the conductor is $I=0.5A$
2. Resistance of the conductor is $R=5\Omega$

Formula:

According to Ohm's law, the formula to calculate the potential difference at the ends of the conductor is

$V=IR$

Step 2: Finding the potential difference at the ends of the conductor

Substituting the values of current and resistance into the formula to calculate the potential difference.

$$\begin{gathered} V=\left(0.5A\right)\left(5\Omega \right) \\ V=2.5\text{volts} \end{gathered}$$

Hence, the potential difference at the ends of the conductor is $2.5\text{volts}$.
