Lesson 1

Use Hand Tools

LEARNING OUTCOMES: At the end of this Lesson, you are expected to do the following:

  • LO 1. prepare hand tools; and

  • LO 2. use appropriate hand tools and test equipment.

Definition of Terms

  • Accidental - occurring unexpectedly, unintentionally, or by chance.

  • Alternating current - an electric current that is continually varying in value and

  • reversing its direction of flow at regular interval

  • Anode - a positive electrode of semiconductor device

  • Capacitance - a property that exists whenever two conductors are separated by

  • insulating material, permitting the storage of electricity

  • Capacitor - a component designed intentionally to have a definite amount of

  • capacitance

  • Circuit - an arrangement of one or more complete paths of electron flow.

  • Conductor - a wire, cable, or other body or medium that is suitable for carrying

  • electric current

  • Current - the rate of transfer of electricity from one point to another

  • Desoldering - a process of unsoldering unwanted parts or components in the circuit

  • with the support of soldering tool

  • Dielectric material - a material that serves as insulator because it has poor electric

  • conductivity

  • Direct current - an electric current that flows in one direction

  • Discrete components- separated or individual components

  • Electronics - a branch of science and technology that deals with the controlled flow of electrons

  • Flammable - tending to burn quickly

  • Hazards - risks; dangers

  • Malfunction - not in normal functionality

  • Ohmmeter - an instrument that measures the amount of resistance in certain component or circuits

  • Resistance - the opposition that a component or material offers to the flow current

  • Resistor – a component designed intentionally to have a definite amount of resistance

  • Soldering - a process of joining two metals caused by heat

  • Soldering technique - a right process in which the solder (lead) is being applied in a connection or in the printed circuit board

  • Splicing – connecting two lengths of conductor

  • Technician - a person skilled in mechanical or industrial techniques or in a particular technical field

  • Tool kit - a small bag or box equipped with hand tools

  • Troubleshooting - identifying and repairing faults in equipment

  • Voltage - the electrical pressure that existed between two points and capable of producing a flow of current when a close circuit is connected between the points.

  • Voltmeter - an instrument that measures the amount of electromotive force in a component or circuit.
