strømnegativ

Strømnegativ is a term used in electricity and electronics to describe a component or a part of a circuit that consumes or absorbs electrical power. When current flows through a strømnegativ element, it converts electrical energy into another form, such as heat, light, or mechanical work. This is in contrast to strømpostiv elements, which generate or supply electrical power, such as batteries or power supplies.

Common examples of strømnegativ components include resistors, which dissipate energy as heat, and light bulbs, which convert electrical energy into light and heat. Motors are also strømnegativ, as they transform electrical energy into kinetic energy to perform work. Diodes, while having complex behavior, can also act as strømnegativ elements in certain operating conditions. Understanding whether a component is strømnegativ is crucial for circuit analysis and design, as it determines the direction of power flow and the overall energy balance of the system. The sum of power consumed by all strømnegativ components in a closed circuit must equal the power supplied by all strømpostiv components, according to the principle of conservation of energy.
