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

65% Answer Correctly

	step-up transformer
	step-down transformer
	transistor
	capacitor

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.

Direct current flows from the __________ terminal of the voltage source to the __________ terminal.

62% Answer Correctly

	positive, positive
	negative, negative
	positive, negative
	negative, positive

Solution

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.

Electrons will flow as current from areas of __________ potential (concentration of electrons) to areas of __________ potential.

74% Answer Correctly

	low, high
	high, high
	high, low
	low, low

Solution

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.

This circuit diagram represents a(n):

69% Answer Correctly

	open circuit
	series circuit
	series-parallel circuit
	parallel circuit

Solution

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.

An engineer who wants to document an electric circuit would create which of the following?

67% Answer Correctly

	a matrix
	a layout
	a blueprint
	a schematic

Solution

A schematic is the proper name for a drawing of an electric or electronic circuit.
