What is the relationship expressed in the voltage formula?

• A. Voltage increases with increased charge only
• B. Voltage is constant regardless of work done
• C. Voltage is work done divided by charge
• D. Voltage affects resistance but not current

Answer: (C)

The voltage formula, represented as \( V = \frac{W}{Q} \), where \( V \) stands for voltage, \( W \) for work done, and \( Q \) for charge, shows that voltage is directly proportional to the amount of work done per unit of charge. This means that if you perform more work on a certain amount of charge, the voltage increases. Therefore, understanding this formula highlights how voltage is fundamentally related to the work required to move charged particles in an electric field, making option C the correct choice. This relationship is central to concepts in electricity, as it helps explain how energy is transferred and utilized in electrical circuits.
