WHAT IS IT!!

In assembling and troubleshooting electronic and electrical circuits, one must acquire knowledge on how to use the hand tools and equipment required for the task. Each of these hand tools and equipment does one or more specific job in connecting, replacing, securing and repairing of electronic circuits.

Basic Component

of Circuit

• AC/DC source

• Fuse

• Wires and cables

• Switch

• Load

AC/DC SOURCE

■ Equipment that will operate on either an AC or DC power source

■ Battery – a DC voltage source containing two or more cells that convert chemical energy to electrical energy.

■ Cell- single unit used to convert chemical energy into a DC electrical voltage.

FUSE

■ It is a safety device used to protect an electrical circuit from the effect of excessive current. Its essential component is usually a strip of metal that will melt at a given temperature.

WIRES AND CABLES

■ A wire is a conductor suitable for carrying an electric current. It is a single slender rod or filament of drawn metal.

SWITCH

■ The switch is a mechanical device used to connect and disconnect a circuit. It breaks an electric current or transfer it to another conductor. Switches are commonly used to open or close a circuit.

LOAD

A source drives the load. Whatever component or piece of equipment is connected to a source and draws current from a source is called load such as bulb and appliances.

Electrical Splices and Joints

When two electric wires are joined together, the joint formed is normally called a splice.

A good splice should not only be mechanically secure, it must also form an electrical connection which is just as efficient conductor as the wire itself.

Three set of splices 

• The Pigtail or rat tail splice is most often used when wires are joined inside an electrical outlet box where wires come together in an electrical appliance.

• The Western union splice is used whenever two lengths of wire are to be joined end-to-end and it is designed for jobs where strain or pull being applied to the wires after the joint had been made.

• The Tap or branch splice is used whenever a second wire must be connected at right angles, or when a wire must be tapped into a continuous main wire.
