Sähköyksiköt

Sähköyksiköt, or electrical units, are standardized quantities used to measure electrical phenomena. The International System of Units (SI) defines these fundamental units. The ampere (A) is the SI base unit of electric current, representing the flow of electric charge. The volt (V) is the SI derived unit of electric potential difference, also known as voltage, measuring the energy per unit charge. Resistance, a measure of opposition to current flow, is quantified in ohms (Ω). Power, the rate at which electrical energy is transferred, is measured in watts (W). Energy itself, the capacity to do work, is expressed in joules (J), though kilowatt-hours (kWh) are commonly used for electrical energy consumption. Capacitance, the ability of a system to store an electric charge, is measured in farads (F). Inductance, the property of an electrical conductor to oppose a change in the electric current flowing through it, is measured in henries (H). These units form the basis for understanding and quantifying all electrical circuits and phenomena.
