This circuit component symbol represents a(n):

71% Answer Correctly

	transistor
	diode
	inductor
	capacitor

Solution

A diode allows current to pass easily in one direction and blocks current in the other direction. Diodes are commonly used for rectification which is the conversion of alternating current (AC) into direct current (DC). Because a diode only allows current flow in one direction, it will pass either the upper or lower half of AC waves (half-wave rectification) creating pulsating DC. Multiple diodes can be connected together to utilize both halves of the AC signal in full-wave rectification.

2 What's the overall power consumption of a piece of equipment that is rated for 4 amps at 130 volts?

80% Answer Correctly

	572 W
	520 W
	173 W
	522 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 130 volts (V) so the equation becomes P = \( 130 \times 4 \) = 520 W

Which of the following is not a purpose of a resistor in an electrical circuit?

70% Answer Correctly

	multiply the current in the circuit
	limit the current in the circuit
	control the voltage in the circuit
	moderate the heat in the circuit

Solution

Resistors can be chosen in a wide variety of values to control the voltage in a circuit, limit the current, or moderate the heat produced by the components in the circuit.

Alternating current changes __________ many times each second.

72% Answer Correctly

	direction
	frequency
	period
	resistance

Solution

In contrast to the constant one-way flow of direct current, alternating current changes direction many times each second. Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances.

A diode to an electronic circuit is like a _______________ to a city?

67% Answer Correctly

	highway
	traffic light
	parking lot
	one-way street

Solution

A diode allows current to pass easily in one direction and blocks current in the other direction.
