Hello and thank you for posting the question to Brainmass.

The potential across the 6 ohms resistor is: V=IR=4*6=24V

The 6 ohms resistor is connected in parellel to the 8 ohms resistor - hence the potential across the 8 ohms resistor is the same as the potential across the 6 ohms resistor, namely 24V
