ELECTRONICS
• The basis of electronics is the controlled movement of electrons through a circuit, usually consisting of a power supply, circuit board, wires, and a series of components.

BATTERIES are used in a wide range of applications and come in a diverse range of size and shape
![Page 20: ELECTRONICS WHAT DOES ‘ELECTRONICS’ MEAN TO YOU ?](https://reader030.vdocuments.site/reader030/viewer/2022012822/56649e7d5503460f94b7f527/html5/thumbnails/20.jpg)
BATTERIES
Batteries provide the force to create the flow of electrons ( I, current ) in most small circuits.
(RED)(BLACK) BATTERY SYMBOL
A battery can be compared to a water pump that forces water through a pipe.
The pressure of the pump can be compared
to voltage ( V ) of a battery.

RESISTORS• Resistors reduce the
amount of current flow in a circuit, and is similar to kinking a hose - it reduces the flow of water.
• Resistor come in many different values (measured in OHMS, Ω) The higher the value the more the current flow is reduced.

Resistors also come in a variety of sizes and types.

L.E.D (Light Emitting Diode)
L.E.D.s are used in place of small light bulbs.
They use less power, cost less, and last for 50,000 hours (approx)

L.E.D SYMBOL
• An L.E.D. is a special type of diode that gives off light. As it is a diode it only conducts electricty in one direction and it has to be inserted the right way round. (Polarity)
L.E.D (Light Emitting Diode)
The short leg is the Negative leg.

TRANSISTOR
A Tansistor is used as an amplifier or a switch.
It uses a very small current to then ‘turn on’ a larger, more useful current, which can be used to then power a light or a speaker.

Printed Circuit Board (PCB)
Usually a fibre- glass panel that has a copper coating. This copper coating is sreen printed and then acid etched to form tracks through which electricity can flow.

The various components and wires are inserted through the holes and soldered into place
