Question

The circuit diagram shows a circuit containing several different components.


Which correctly describes the number of one type of component in this circuit?

A. two batteries
B. two switches
C. three bulbs
D. three resistors

Answer 1

The long-short line pair represents a battery and the wiggly line represents a resistor so there are two batteries and three resistors in the circuit. The answers are A and D. 

Answer 2

Answer: D. Three resistors

Explanation:

A bulb is represented by cross inside a circle. A battery is represented by alternate small and big straight lines. A closed switch is given by a straight line between two small circles. An ammeter is represented by alphabet A inside a circle. A zig-zag line represents resistance.

The given circuit diagram has two bulbs, one switch, one ammeter, one battery and three resistors. The two resistors are connected in series with another one in parallel.

Thus, the correct option is D. three resistors.
