Review

An amplifier is most similar in function to which of the following:

65% Answer Correctly

	capacitor
	step-down transformer
	step-up transformer
	transistor

Solution

An amplifier is a device that takes a small input signal and creates a larger output signal. This makes it most similar to a step-up transformer which takes a smaller input voltage and creates a larger output voltage.

Capacitors store:

68% Answer Correctly

	capacitance
	resistance
	current
	electricity

Solution

Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.

3 What's the overall power consumption of a piece of equipment that is rated for 6 amps at 80 volts?

80% Answer Correctly

	960 W
	483 W
	480 W
	160 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 6 amps (I) at 80 volts (V) so the equation becomes P = \( 80 \times 6 \) = 480 W

Longer the electrical wires mean _______________ voltage drop.

73% Answer Correctly

	diminishing
	complete
	greater
	lesser

Solution

Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.

This circuit diagram represents a(n):

65% Answer Correctly

	series circuit
	rectifier
	parallel circuit
	series-parallel circuit

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.
