1

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

67% Answer Correctly

integrated circuits

series circuits

series-parallel circuits

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 __________ electric current produces a magnetic field proportional to the amount of current flow.

61% Answer Correctly

high voltage

moving

low voltage

stationary
Solution

A moving electric current produces a magnetic field proportional to the amount of current flow. This magnetic field can be made stronger by winding the wire into a coil and further enhanced if done around an iron containing (ferrous) core.

3

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

70% Answer Correctly

is recommended

is required

makes no difference

makes the circuit less safe
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.

4

The joule is a unit of measurement for:

67% Answer Correctly

power

resistance

capacitance

energy
Solution

The joule is a unit of measurement for energy.

5

Which of the following statements about electrical resistance is true?

74% Answer Correctly

the less resistive the conductor is the slower electron flow will be

electrically conductive materials have no resistive properties

the more resistive the conductor is the slower electron flow will be

the more resistive the conductor is the faster electron flow will be
Solution

Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.
