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?

Answer

Explanation:

Step1: Recall circuit - type definitions

In a series circuit, components are connected end - to - end in a single path. In a parallel circuit, components are connected across common points. Circuit A has components connected end - to - end, so it is a series circuit. Circuit B has components connected across common points, so it is a parallel circuit.

Step2: Recall voltage and brightness relationship

In a parallel circuit, each component has the full battery voltage across it. In a series circuit, the voltage is divided among the components. Since the brightness of a light bulb is related to the power (P=\frac{V^{2}}{R}) (assuming resistance (R) is constant), and in a parallel circuit each bulb gets the full voltage, the bulbs in a parallel circuit shine at their maximum brightness.

Answer:

Which circuit is a parallel circuit? Circuit B Which circuit is a series circuit? Circuit A In which circuit do the light bulbs all shine at their maximum brightness? Circuit B
