Glossary
Amplifier - An electronic circuit that amplifies the signal that is sent to it. The amplifying component can
be a transistor, vacuum tube or appropriate magnetic device.
Battery - A source of energy. It contains chemicals which will undergo chemical reaction to produce
electricity when a circuit is connected.
Capacitance - A measurement of the capacity of a capacitor for storing electric charge.
Capacitor - A device consists of two conductors that are separated by an insulator. It is designed for
storing electrical charge or as a filter in a circuit.
IC (Integrated Circuit) - A small electronic device made of semiconductor material and is used for a
variety of devices, including microprocessors, electronic equipment and automobiles.
Light Sensor - There are different types of light sensor. The one used here is a phototransistor. When
light falls on it, it is like a switch connected and so current is allowed to pass through it.
Diode – A device used in electric circuitry to allow an electric current to flow in single direction and block
it in the reverse direction.
Microphone - A device converts sound into an electrical signal.
Motor – A device converts electrical energy to mechanical motion.
LED (Light Emitting Diode) - A diode emits light when current is passing through it.
Resistance - A measurement of the degree to which an object opposes an electric current through it.
Resistor - A device designed for possessing resistance.
Speaker - A device that changes electrical signals into sound.
Switch - A device for opening and closing power source to a circuit.
Transistor - A semi-conductor device that amplifies a signal and opens or closes a circuit.
