1 What's the overall power consumption of a piece of equipment that is rated for 4 amps at 150 volts?

80% Answer Correctly

	900 W
	300 W
	540 W
	600 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 150 volts (V) so the equation becomes P = \( 150 \times 4 \) = 600 W

You would measure the amount of voltage between two points in a circuit with a(n):

83% Answer Correctly

	voltmeter
	battery
	ammeter
	reostat

Solution

Voltage (V) is the electrical potential difference between two points. A voltmeter is used to measure the voltage between two points in a circuit.

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

70% Answer Correctly

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

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.

In metals, increasing the temperature typically _____________ conductivity.

50% Answer Correctly

	decreases
	eliminates
	does nothing to
	increases

Solution

All conductors have resistance and the amount of resistance varies with the element. Metals exhibit increased resistance (and, therefore, lower conductivity) as their temperature increases.

Which of the following is not a terminal on a transistor?

59% Answer Correctly

	base
	emitter
	input
	collector

Solution

A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor.
