resistanskomponent

A resistor, also known as a resistanskomponent, is a passive two-terminal electrical component that implements electrical resistance as a circuit element. The current through a resistor is in direct proportion to the voltage across the resistor's terminals. This relationship is represented by Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R), or I = V/R. Resistors are used to reduce current flow, adjust signal levels, divide voltages, bias active elements, and terminate transmission lines, among other uses. They are available in a wide range of values and package sizes, from tiny surface-mount devices to large power resistors. Resistors can be made from various materials, including carbon, metal film, and wire-wound, each with its own characteristics and applications. The resistance value is typically marked with colored bands or a numeric code. Resistors are fundamental components in electronic circuits and are used in virtually every electronic device.
