What is the work done by one coulomb of electricity when moving through a potential difference of one volt?

• A. Joule
• B. Watt
• C. Voltmeter
• D. Ohm

Answer: (A)

When one coulomb of electricity moves through a potential difference of one volt, it performs work measured in joules. This relationship is defined by the formula: Work (in joules) = Charge (in coulombs) × Voltage (in volts) So, when one coulomb of charge moves through a potential difference of one volt, the work done is: 1 coulomb × 1 volt = 1 joule This means that if a charge of one coulomb moves through a potential difference resulting in an energy change of one joule, it effectively tells us how much energy is required to move that charge through that potential difference. Understanding this concept is crucial because it lays the foundation for calculating energy transfer in electrical systems, which is a key principle in electrical engineering and physics.

So, when one coulomb of charge moves through a potential difference of one volt, the work done is:

This means that if a charge of one coulomb moves through a potential difference resulting in an energy change of one joule, it effectively tells us how much energy is required to move that charge through that potential difference.
