The Ampere (A) is the unit of electric current. The passage of one Coulomb of charge through a conductor per second is known as one ampere. The Volt (V) is the unit of voltage. The electric potential energy per unit charge in an electric circuit is measured by voltage. The Farad (F) is the capacitance unit. The Tesla (T) is the magnetic field unit. The strength of a Magnetic field is represented by the Tesla, the SI unit of Magnetic flux density.
