How much work is done when one coulomb charge moves against a potential difference of 1 volt? A potential of one volt appears across a resistance of one ohm when a current of one ampere flows through that resistance. Most commercially manufactured voltmeters have several scales, increasing in powers of 10; for example, 0-1 … Voltage . What does volt-amps mean? The charge has passed round the whole circuit and 'given' its energy to the components in the circuit by the time it reaches the battery so it needs to get some more. It means that an object having a resistance of 1ohm allows 1 ampere of current to flow through 2 points having potential difference of 1 volt.

Other units of power include ergs per second, horsepower, metric horsepower or cheval vapeur (CV)), and foot-pounds per minute. Afraid of a subject or a topic? Solve for currents, voltages, and powers in simple circuits. Potential of a point is said to be one volt if 1 Joule of work is done in moving 1 coulomb of positive charge from infinity to that point against the electric intensity. https://study.com/academy/lesson/voltage-current-lesson-for-kids.html If a unit of electrical charge were placed in a location, the voltage indicates the potential energy of it at that point. 2. It is equal to 1 volt upon 1 ampere. This difference in charge between the two points is called voltage. Voltage is a representation of the electric potential energy per unit charge. Potential of a point is said to be one volt if 1 Joule of work is done in moving 1 coulomb of positive charge from infinity to that point against the electric intensity. The watt unit is named after James Watt, the inventor of the steam engine.
