Question

use the diagram and drop - down menus to answer each question.
which circuit is a parallel circuit?
which circuit is a series circuit?
in which circuit do the light bulbs all shine at their maximum brightness?

Explanation:

Question 1: Which circuit is a parallel circuit?

A parallel circuit has components (like light bulbs) connected across the same voltage source, with multiple paths for current. Circuit B has three bulbs connected in parallel (each on its own branch), so it's the parallel circuit.

A series circuit has components connected in a single path, so current flows through each component one after another. Circuit A has three bulbs in a single loop (series), so it's the series circuit.

In a parallel circuit, each component (bulb) gets the full voltage of the source, so they operate at maximum brightness. In series, voltage is divided, so bulbs are dimmer. Circuit B is parallel, so bulbs there shine at max brightness.

Answer:

Circuit B

Question 2: Which circuit is a series circuit?
