are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

is a device that stores electrical energy in an electric field.

also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil.

- is a device that regulates current or voltage flow and acts as a switch or gate for electronic signals

is an electrical device that trades voltage for current in a circuit, while not affecting the total electrical power

or scopes) test and display voltage signals as waveforms, visual representations of the variation of voltage over time. The signals are plotted on a graph, which shows how the signal changes.

this is used to set the range selector in any range in the 2nd quadrant of the panel which is marked “DCV”.

- this is used to set the range selector in any range in the 1st quadrant of the panel which is marked “ACV”.

this is used to set the range selector in any range in the 3rd quadrant of the panel which is marked “DCmA”.

this is used to set the range selector in any range in the 4th quadrant of the panel which is marked “Ω
