The circuit diagram shows a circuit containing several different components.

Question

A diagram of a circuit with the power source in the middle. Just above that are two small circles. It then branches left and right. In both directions, is a circle with an X in it and a resistor. Past the resistor on one path is a second resistor and on the other path a circle with an A in it. Both paths join again right before the power source.
Which correctly describes the number of one type of component in this circuit?

two batteries
two switches
three bulbs
three resistors

Answer 1

Based on your description of the circuit diagram, it sounds like you have the following components:

1. Two small circles that likely represent batteries (since you mentioned a power source in the middle).
2. Two components with an "X" in them, which likely refer to bulbs (light sources).
3. Two resistors, one on each branch.
4. A second resistor on one path and a circle with an "A" in it on the other path, which could represent an ammeter or some other component.

Given this layout, here's a breakdown:

• Batteries: 2
• Switches: 0 (not mentioned in your description)
• Bulbs: 2 (indicated by the X in the circles)
• Resistors: 3 (two on the branches and one mentioned afterward)

So the correct description based on your details would be three resistors.
