Question | Answer |
---|---|
CIRCUIT | A group of components that perform a specific function. |
RESISTOR | A component that is used to strict (limit) current. |
SCHEMATIC DIAGRAMS | Drawings that show you how the components in a circuit are interconnected. |
CAPACITOR | A component that stores energy in a an electrical field, also called a condenser. |
INDUCTOR | A component that stores energy in a magnetic field, also called a coil or a choke. |
TRANSFORMER | A component that contains one or more inductors that are wrapped around a single physical structure. |
STEP DOWN TRANSFORMER | A transformer that decreases its input voltage to a lower level. |
STEP UP TRANSFORMER | A transformer that increases its input voltage to a higher level. |
SWITCH | A component that is used to make or break an electrical connection. |
FUSE | A component that automatically breaks an electrical connection if the current increases beyond a certain value. |
CIRCUIT BREAKER | A component that can be reset and used again after breaking a current path. |
DIGITAL MULTIMETER (DMM) | A meter that measures three of the most basic electrical properties: voltage, current and resistance. |
VOLT-OHM-MILLIMETER (VOM) | A meter that uses an analog scale (rather than a digital scale) to provide a readout. |
FREQUENCY COUNTER | A piece of equipment that indicates the number of times certain events occur every second. |
FUNCTION GENERATOR | A piece of equipment that generates a variety of waveforms. |
OSCILLOSCOPE | A piece of test equipment that provides a visual display for voltage and time measurements. |
ENGENEERING NOTATION | A short hand method of representing large and small numbers. |
FUNCTION SELECT | A control that sets the multi-meter to measure volts(v), amperes(A), or Ohms (Ω) |
