Question

name: ______ date: monday

1. according to the text, what is the second component of a circuit?

a. electric current
b. energy source
c. energy recipient
d. wire or cable

1. two diagrams are featured in the text. what role do these two diagrams play?

a. they illustrate two types of circuits that are described in the text.
b. they contradict the information described in the text about series and parallel circuits
c. they illustrate how series and parallel circuits combine to form a combination circuit.
d. they illustrate information about circuits not discussed in the text.

1. read this paragraph from the text.

in practice, most electrical devices have combination circuits. combination circuits do not use just one type of circuit. instead, combination circuits utilize both series and parallel types. devices that use combination circuits include computers and television sets. more complex circuits often have more electric components like switches and resistors, which limit the electric current flow.
what can you conclude based on this evidence?
a. all electronic devices use combination circuits.
b. different devices use different types of circuits.
c. electronic devices only use combination circuits.
d. resistors are required for parallel circuits.

1. based on the text, what would happen if one light went out in a parallel circuit?

a. all of the lights would go out.
b. the circuit would become a simple circuit.
c. all the lights except for that one would stay lit.
d. the energy source would stop working.

Explanation:

Question 1

To answer, we recall circuit components. A circuit typically has an energy source (first), then wires/cables to conduct, then energy recipient, etc. So the second component is wire or cable (option D).

Diagrams in texts about circuits (series/parallel) usually illustrate the types described. Option A says they illustrate two types described, which is correct. B is wrong (no contradiction), C is wrong (they don't show combination from series/parallel), D is wrong (they discuss text - related circuits).

The text says most devices have combination circuits, some use series/parallel, and complex have more components. Option A is wrong (not all), C is wrong (not only combination), D is wrong (resistors for complex, not just parallel). B is correct as different devices (computers, TVs, complex) use different (combination, series, parallel) circuits.

Answer:

D. wire or cable
