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

67% Answer Correctly

integrated circuits

parallel circuits

series 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 10-amp circuit breaker. What is the largest number of watts loads on this circuit can safely use?
82% Answer Correctly
1203 W
1080 W
1206 W
1200 W
Solution
Wattage is current multiplied by voltage: W = IV. So, the maximum amount of power a 120-volt circuit with a 10A circuit breaker would allow is 120V x 10A = 1200 W.

This circuit component symbol represents a(n):

65% Answer Correctly

diode

potentiometer

capacitor

fuse
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.

4

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

62% Answer Correctly

negative, negative

positive, negative

positive, positive

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.

One of the lights on your Christmas tree burns out and this causes the rest of the lights connected to that strand to go dark. How are the lights in that strand connected?

73% Answer Correctly

series-parallel

parallel

series

perpendicular
Solution

Lights connected in series form a chain with each light connecting to adjacent lights via one wire. Therefore, if one of the lights burns out and breaks the series, none of the other lights will receive power and they'll go dark. Lights connected in parallel each connect to the positive and negative nodes of the power source and would not go dark if one of their neighbors burnt out.
