Electricity cannot flow...

72% Answer Correctly

	through a circuit under load
	through an open circuit
	through a closed circuit
	through a circuit with resistance

Solution

An electrical circuit is a path through which electricity flows. This path contains one or more components that create a load (something that is using electricity) and that load acts as resistance to the passage of electricity through the circuit. Electricity can only flow through a circuit when the path is closed and cannot flow through an open circuit.

The diameter of a number 12 wire is __________ the diameter of a number 6 wire?

52% Answer Correctly

	double
	triple
	less than
	more than

Solution

The larger the number the smaller the diameter of the wire. So, the diameter of a number 12 wire is less than the diameter of a number 6 wire.

The hertz is a unit of measurement for:

81% Answer Correctly

	energy
	power
	inductance
	frequency

Solution

The hertz is a unit of measurement for frequency.

4 What's the overall power consumption of a piece of equipment that is rated for 4 amps at 20 volts?

80% Answer Correctly

	88 W
	80 W
	83 W
	79 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 4 amps (I) at 20 volts (V) so the equation becomes P = \( 20 \times 4 \) = 80 W

An inductor __________ changes in the electric current flowing through it.

61% Answer Correctly

	doubles
	eliminates
	resists
	enhances

Solution

An inductor is coiled wire that stores electric energy in the form of magnetic energy and resists changes in the electric current flowing through it. If current is increasing, the inductor produces a voltage that slows the increase and, if current is decreasing, the magnetic energy in the coil opposes the decrease to keep the current flowing longer. In contrast to capacitors, inductors allow DC to pass easily but resist the flow of AC.
