In order to calculate the potential difference (also known as voltage) across a resistor in an electrical circuit, you would need to know the current flowing through the resistor and the resistance value of the resistor. The potential difference (V) across a resistor is related to the current (I) flowing through it and the resistance (R) of the resistor by the equation: V = IR.
If we know the resistance of the 10 ohm resistor and the current flowing through it, we could calculate the potential difference across it. However, without more information about the circuit, it is not possible to determine the potential difference across the 10 ohm resistor.
