Question

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 solve this, we analyze each option. An electric current is the flow, not a component (eliminate A). The energy source is typically the first component. The second component related to circuit structure (like connecting or receiving) – wire or cable is for connection, but the energy recipient (load) or wire? Wait, standard circuit components: energy source (battery), then wires, then load. Wait, maybe the text's order: if first is energy source, second could be wire or cable (D) or energy recipient? Wait, no – let's think. The options: B is energy source (first), so second would be wire (D) or recipient? Wait, maybe the text says components like energy source, wire, recipient. So second is wire or cable (D).

Diagrams in circuit texts usually illustrate concepts. Option A: they illustrate two types (series/parallel) described – that makes sense. B: contradict? No. C: combine to form combination? No, diagrams show series and parallel, not combination. D: not discussed? No. So A is correct.

The paragraph says most devices have combination, some use series/parallel, complex have more components. Option A: "all" is wrong (most, not all). B: different devices use different types (combination, series, parallel, complex) – correct. C: "only" combination? No, some use series/parallel. D: resistors for parallel? The text says complex have resistors, not specific to parallel. So B is correct.

Answer:

D. wire or cable
