Question:medium
The resistance of a wire is \( 10 \, \Omega \) and the current passing through it is \( 2 \, \text{A} \). What is the potential difference across the wire?
The resistance of a wire is \( 10 \, \Omega \) and the current passing through it is \( 2 \, \text{A} \). What is the potential difference across the wire?
Show Hint
Use Ohm's law \( V = IR \) to calculate the potential difference when you know the current and resistance.
