The diameter of a number 12 wire is __________ the diameter of a number 6 wire?

52% Answer Correctly

	double
	triple
	less than
	more than

Solution

The larger the number the smaller the diameter of the wire. So, the diameter of a number 12 wire is less than the diameter of a number 6 wire.

2 Use Ohm's Law to calculate the value of voltage in this circuit if resistance is 100 Ω and current is 7.5 amps.

85% Answer Correctly

	1125 V
	750 V
	753 V
	375 V

Solution

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.

V = \( I \times R \) = \( 7.5 \times 100 \) = 750 V

Which of these materials is not a good conductor of electricity?

79% Answer Correctly

	copper
	gold
	air
	tin

Solution

All conductors have resistance and the amount of resistance varies with the element. In general, metals make the best conductors of electricity and non-metals make the worst conductors of electricity.

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

67% Answer Correctly

	a blueprint
	a matrix
	a schematic
	a layout

Solution

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

A capacitor to an electronic circuit is like a _______________ to a house?

67% Answer Correctly

	storage shed
	safe
	driveway
	gate

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.
