ELECTRONIC SYMBOL II

Diode Type-light-Also called LEDs used for emitting light.

Diode-Schottky-a semiconductor diode with a low forward voltage

Earth Ground-To throw away additional current to earth.

Exclusive OR-It is a type of OR gate only.

Integrated Circuit-It contains thousands of transistors within it.

Rectifier-electrical device that converts alternating current (AC) to direct current (DC).

Relay-electrical switch that opens and closes under the control of another electrical circuit.

Rheostat-A rheostat is a two-terminal variable resistor

Resistors-A resistor is a two-terminal electronic component that opposes an electric current by producing a voltage drop between its terminals in proportion to the current,

Solar Cell-Used to generate Solar energy.

Transformer-To transform high AC To low AC and vice versa.
