An ampere (A) is the unit of measurement for electric current. It measures the amount of electrical current flowing through a circuit during a specific time interval. The ampere is named after André-Marie Ampère, a French mathematician and physicist who was one of the main discoverers of electromagnetism.

Ohm (Ω) is the unit of measurement for electric resistance, which is the opposition to the flow of an electric current through a circuit.

Volt (V) is the unit of measurement for electric potential difference, which is the energy required per unit charge to move a test charge between two places in a static electric field.

Watt (W) is the unit of measurement for power, which is the rate at which energy is used or generated in an electrical circuit.
