What is ampere?

• An ampere is the amount of current produced by the force of one volt acting through a resistance of one ohm. It is one of the seven basic SI units.The amount of current flowing through the wire is measured in amperes, or amps. The equivalent of available electricity at the power source is voltage, or volts.
• If we divide the watts of a given electrical item by the total number of volts available from the electric outlet to calculate amperage drawn by the wire.
• Current is usually denoted by the symbol I. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR.
• An alternative statement of Ohm's law is I = V/R.
