• Ampere


  Basic unit of current
• Current


  The flow of electrons moving in a given direction
• Electronic measuring instrument


  Portable instruments used to measure electrical quantities such as current, voltage, and resistance
• Ohmmeter


  An electronic instrument used to measure resistance of a component or the entire circuit
• Ohmmeter scale


  Section of the ohmmeter where the value of the resistance is being indicated
• Range multiplier


  A portion in the ohmmeter where the actual reading is multiplied by the range value
• Resistance


  The opposition to the flow of electrons
• Resistor


  An electronic component that is used to offer opposition to current in an electrical circuit
• Resistor color coding


  A scheme to determine the value of resistors by color bands printed on their bodies as code
• Test Probes


  Connectors connected to terminals of the VOM and component's terminals or test points in a circuit to be tested. They are oftentimes red and black in color
• Tolerance


  The fourth color in the 3-band color coding that indicates the percentage of deviation from its color coded value
• Volt


  Basic unit of voltage
• Voltage


  An electrical pressure that pushes current to flow within a load through a conductor
• Zero-ohm adjuster


  Part of the ohmmeter that is used in adjusting the pointer of the ohmmeter to zero before resistance measurements or continuity tests are made
• 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 intervals
• 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
