By what other name is the unit joule/coulomb called ?
Answers
1 Answer. The other name of unit joule/coulomb is called Volt.
Answer:
Explanation:
The other name of unit joule/coulomb is called Volt.
Potential energy of a charge system : U = q V = work done in bringing a charge q from infinity to to a point with potential V.
So Joule = Coulomb * Volt J/C = Volt
Answer:
The other name of joule/coulomb is called volt.
Explanation:
Energy has unit Joule. By the definition, Power is rate at which energy is transformed. As the unit of Power which is Watt, W = Joule/Second.
Therefore Joule = Watt x Second
But we know that, Power = Voltage x Current
Therefore Joule = Voltage x Ampere x Second --(1)
Moreover, rate of change of charge is current. Therefore Ampere = Coulomb/Second
So Coulomb = Ampere x Second --(2)
Substituting (2) into (1),
Joule = Voltage x Coulomb.
Therefore Joule/Coulomb = Voltage
Hence the other name of Joule/Coulomb is Volt.
