What kind of diode allows current to flow in the opposite direction once a certain voltage threshold is reached?

51% Answer Correctly

	v-type diode
	light emitting diode
	zener diode
	standard diode

Solution

A diode allows current to pass easily in one direction and blocks current in the other direction. A zener diode is a diode which allows current to flow in one direction as normal and will also allow current flow in the reverse direction when the voltage is above a certain value. This value is called the breakdown voltage.

2 What's the overall power consumption of a piece of equipment that is rated for 5 amps at 130 volts?

80% Answer Correctly

	650 W
	652 W
	975 W
	651.5 W

Solution

Power is measured in watts (W) and 1 watt equals 1 ampere multiplied by 1 volt: P = \( V \times I \). For this problem, the equipment is rated for 5 amps (I) at 130 volts (V) so the equation becomes P = \( 130 \times 5 \) = 650 W

Which of the following is the preferred method for splicing wires?

57% Answer Correctly

	wrap in small gauge wire
	wire crimps
	soldering
	screw-on connectors

Solution

Splicing is permanently joining two wires together. Splicing can be done with screw-on connectors or wire crimps but the preferred method for splicing is soldering. Soldering takes the most effort but results in a connection that is electrically and mechanically identical to the original wire.

This circuit diagram represents a(n):

69% Answer Correctly

	series circuit
	series-parallel circuit
	parallel circuit
	open circuit

Solution

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.

The joule is a unit of measurement for:

67% Answer Correctly

	resistance
	capacitance
	energy
	power

Solution

The joule is a unit of measurement for energy.
