5. AC
Alternating current describes the flow of charge that changes direction periodically.
As a result, the voltage level also reverses along with the current.

17. Multimeter/AVO meter
A multimeter is a device used to measure voltage, resistance and current in electronics & electrical equipment.
It is also used to test continuity between to 2 points to verify if there is any breaks in circuit or line.
There are two types of multimeter Analog & Digital
Analog has a needle style gauge
Digital has a LCD display

19. Multimeter/AVO meter
Red meter lead Is connected to Voltage/Resistance or amperage port and Is considered the positive connection
Black meter lead Is always connected to the common port and Is considered the negative connection
Probes Are the handles used to hold tip on the tested connection
Tips Are at the end of the probe and provides a connection point

28. Rheostat
It is an adjustable or variable resistor. It is used to control the electrical resistance of a circuit without interrupting the flow of current. Rheostat has 3 terminals and usually consist of a resistive wire wrapped to form a toroid coil with a wiper that slides along the surface of the coil.

29. Capacitor
A capacitor is a passive two-terminal electrical component that stores electrical energy in an electric field. The effect of a capacitor is known as capacitance.

30. Ballast
An electrical ballast is a device placed in line with the load to limit the amount of current in an electrical circuit. It may be a fixed or variable resistor.
A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance artifact in the tube's voltage-current characteristic.
