1 What's the overall power consumption of a piece of equipment that is rated for 5 amps at 120 volts?

92% Answer Correctly

	300 W
	600 W
	200 W
	602 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 5 amps (I) at 120 volts (V) so the equation becomes P = \( 120 \times 5 \) = 600 W

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

67% Answer Correctly

	series-parallel circuits
	integrated circuits
	series 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.

Which of the following is not a characteristic of a step-up transformer?

54% Answer Correctly

	the secondary voltage is higher than the primary voltage
	increases voltage
	the primary voltage is higher than the secondary voltage
	has more turns in the secondary winding than in the primary winding

Solution

As their names indicate, a step-up transformer is used to step up or increase voltage and a step-down transformer is used to step down or decrease voltage. In a step-up transformer, the secondary voltage is higher than the primary voltage and it has more turns in the secondary winding than in the primary winding.

4 How would you connect 4 [15V 25A] batteries to achieve a combined power output of 60V 25A?

52% Answer Correctly

	series
	perpendicular
	orthogonal
	series-parallel

Solution

Connecting the 4 batteries in series multiplies their voltage while keeping their current the same yielding a 60V 25A configuration. Connecting the 4 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 15V 100A configuration. Using a series-parallel connection, 2 batteries can be connected in series and 2 can be connected in parallel resulting in a 30V 50A configuration.

Current is the rate of flow of electrons per unit time and is measured in:

69% Answer Correctly

	ohms
	amperes
	volts
	coulombs

Solution

Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.
