5.3 Circuits

Question 1

In electrical devices, wires form a pathway for electron flow, which is called a(n) ____.

Answer 1

Circuit

Question 2

What are the four elements of a simple circuit?

Answer 2

Power source, conductor, load, and device for controlling current

Question 3

What are the three kinds of circuits?

Answer 3

Series, parallel, and complex

Question 4

Series circuit

Answer 4

Provides only one path for current to flow

Question 5

Parallel circuit

Answer 5

Provides two or more paths for current to flow

Question 6

In a series circuit, a nonfunctioning load will ___________.

Answer 6

Stop electrical current in the remainder of the circuit.

Question 7

What are the two main advantages of parallel circuits?

Answer 7

(1) Each branch operates independently, so if one load burns out, the other branches will continue to function.
(2) The current draw of each branch only affects that branch, so you can have small and large loads on the same circuit.

Question 8

With the exceptions of switches, fuses, and circuit breakers, all residential wiring is done in ______.

Answer 8

Parallel

Question 9

Load

Answer 9

Any device that uses an electric current and converts the energy to another form.

Question 10

Each load is designed to operate at a specific ______.

Answer 10

Voltage
