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.

What is the potential difference in an electrical circuit a measure of?

58% Answer Correctly

	the resistance at a specific location in the circuit
	the voltage at a specific location in the circuit
	the load at a specific location in the circuit
	the current at a specific location in the circuit

Solution

Electrons flow from an area of high concentration to an area of low concentration. A high voltage indicates a high concentration of electrons that creates a greater potential for electron flow than a low voltage. When applied to a load, voltage creates electricity and potential difference is the measure of voltage at a specific location in an electrical circuit.

This circuit diagram represents a(n):

65% Answer Correctly

	series-parallel circuit
	series circuit
	parallel circuit
	rectifier

Solution

In a parallel circuit, each load occupies a separate parallel path in the circuit and the input voltage is fully applied to each path. Unlike a series circuit where current (I) is the same at all points in the circuit, in a parallel circuit, voltage (V) is the same across each parallel branch of the circuit but current differs in each branch depending on the load (resistance) present.

4 What's the overall power consumption of a piece of equipment that is rated for 2 amps at 110 volts?

80% Answer Correctly

	220 W
	221 W
	222 W
	110 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 2 amps (I) at 110 volts (V) so the equation becomes P = \( 110 \times 2 \) = 220 W

Using a fuse with a current rating higher than that required by a circuit:

70% Answer Correctly

	is recommended
	makes the circuit less safe
	is required
	makes no difference

Solution

A fuse is a type of low resistance resistor that stops current flow in a circuit in response to a larger than intended electric current flow. Using a fuse with a higher current rating than required by a circuit is less safe as it could potentially allow overcurrent and risk a fire or heat-related equipment damage.
