Question

What does the diagram show?

A.one battery, two light bulbs, and three resistors
B.one battery, two switches, and three light bulbs
C.one switch, one resistor, and three light bulbs
D.one switch, one light bulb, and three batteries

Answer 1

The battery is the set of vertical lines at the bottom, so there's one battery.
The switches are the line between the small circles (they're closed here) there are 2 of them.
The circles with Xs inside are bulbs.
So B is correct.

Answer 2

Answer: B.one battery, two switches, and three light bulbs

Step-by-step explanation:

A battery is represented by alternate small and big straight lines. The given circuit diagram has one battery.

A bulb is represented by a cross in a circle. The given circuit diagram has three bulb.

A closed switch is represented by a straight line connecting two small circles. Thus, the given circuit has two switches.
