Electronic components

Capacitor

A capacitor is a passive two-terminal electrical component used to temporarily store energy in an electric field. Size of a capacitor is measured in micro farads (uf).

ground

A common return path for electric current. Can also be referred to as negative side of a battery or power source in electronics.

variable resistor

A device used to vary (change) resistance in a circuit.

LED

A light-emitting diode (LED) is a semiconductor light source.

photo resistor

A photoresistor or light dependent resistor (LDR) is a resistor whose resistance changes with changes in light

resistor

A resistor is a device designed to add resistance to a circuit. It's purpose is to slow the flow of electrical current

Schematic symbol

A schematic symbol is a pictogram used to represent various electrical and electronic devices (such as wires, batteries, resistors, and transistors) in a schematic diagram of an electrical or electronic circuit.

Integrated Circuit

An Integrated chip (IC) is an entire electronic circuit with diodes, transistors wires etc... built into a small piece of silicon. Integrated chips can be used for many different applications depending on the chip.

switches

In electronics, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.

Diode

a type of two terminal electronic component with a non-linear current - voltage characteristic. The most common function of a diode is to allow an electric current pass in one, while blocking current in the opposite direction

Polarized capacitor

has a positive and negative end

Battery

one or more electrochemical cells that convert stored chemical energy into electrical energy; long = positive; short = negative
