sähkötehosta
Sähkötehosta, meaning "electrical power" in Finnish, refers to the rate at which electrical energy is transferred or consumed by an electrical device. It is a fundamental concept in electrical engineering and physics. The unit of electrical power is the watt (W), named after Scottish inventor James Watt. One watt is defined as one joule of energy per second.
In direct current (DC) circuits, electrical power can be calculated by multiplying the voltage across the circuit
In alternating current (AC) circuits, the calculation of power is more complex due to the fluctuating nature
Understanding sähkötehosta is crucial for designing efficient electrical systems, sizing power supplies, and ensuring the safe
