Resistors

Education, Electronics, Uncategorized
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. The main function of a resistor within an electrical or electronic circuit is to oppose or resist the flow of current, hence named as resistor . The symbol of resistor :   Resistance is measured in units called “Ohm”. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as…
