Active components on a source of energy to perform their function. These components can amplify current and can produce a power gain.The following figure lists the different types of active components in a circuit :
Diode
A diode is a specialized electronic component with two terminals known as the anode and the cathode. It has asymmetric conductance, which means that it conducts mainly in one director.It has very less resistance, ideally zero, to the flow of current in one direction whereas it has high resistance, ideally infinite, in the other direction. Diodes are usually made up of semiconductor materials such as germanium, silicon or selenium. Appliances such as germanium, silicone or selenium. Appliances such as microwave oven, water purifier and mixer /juicer/grider have this component. The following image shown diodes:
Transistor
A transistor is an electronic device, made up of semiconductor material. Usually, it consists three or more terminals for connecting to an external circuit. It is utilized to amplify or switch electrical power and electronic signals. Appliances such as microwave oven, water purifier and mixer/juicer/grinder have this component.

IC
An IC, also known as a microchip, is a semiconductor water on which a number of small resistors, capacitors are fabricated. It can work as an oscillator, an appliance such as microwave oven, water purifier and mixer, juicer and grinder has this component. The following image shows an integrated circuit:
LED
An LED is made of a p-n junction diode which releases light when it is activated.It is a two-lead semiconductor source of light. Energy is released as photons when a suitable voltage is applied to the leads. Appliances such as microwave oven, water purifier and mixer /juicer /grinder have this component. The following image shown an LED:
