Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?

67% Answer Correctly

	parallel circuits
	series circuits
	integrated circuits
	series-parallel circuits

Solution

Circuits containing transistors are packaged into integrated circuit chips that allow encapsulating complex circuit designs (CPU, memory, I/O) for easier integration into electronic devices and machines.

2 A circuit with a 120-volt power supply is protected by a 5-amp circuit breaker. What is the largest number of watts loads on this circuit can safely use?

85% Answer Correctly

	601.5 W
	602 W
	600 W
	300 W

Solution

Wattage is current multiplied by voltage: W = IV. So, the maximum amount of power a 120-volt circuit with a 5A circuit breaker would allow is 120V x 5A = 600 W.

The most common circuit configuration is:

58% Answer Correctly

	parallel
	series-parallel
	household
	series

Solution

Circuits are not limited to only series or only parallel configurations. Most circuits contain a mix of series and parallel segments. A good example is a household circuit breaker. Electrical outlets in each section of the house are wired in parallel with the circuit breaker for that section wired in series making it easy to cut off electricity to the parallel parts of the circuit when needed.

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

67% Answer Correctly

	a matrix
	a layout
	a schematic
	a blueprint

Solution

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

Which of the following allows DC to pass easily but resists the flow of AC?

56% Answer Correctly

	semiconductor
	transformer
	inductor
	capacitor

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.
