Active Versus Passive Devices

Electronic component are classed into either being Passive devices or Active devices. Active devices are different from passive devices such as resistors, capacitors and inductors. These devices are capable of changing their operational performance, may deliver power to the circuit, and can perform interesting mathematical functions. While a device that does not require a source of energy for its operation. Examples of passive devices are electrical resistors, electrical capacitors, diodes, opti
