Question

use the voltmeter to measure the voltage in different parts of the series circuit. which of the following best describes how voltage is distributed in this series circuit? o each bulb gets the full voltage from the battery o how much voltage each bulb gets depends on how far away it is from the battery o each bulb gets part of the voltage from the battery

Explanation:

To solve this, we analyze the voltage distribution in a series circuit:

1. Recall the properties of series circuits: In a series circuit with resistors (like bulbs, which have resistance), the total voltage \( V_{total} \) is the sum of the voltage drops across each component (\( V_{total} = V_1 + V_2 + \dots + V_n \)). Each component’s voltage drop depends on its resistance (\( V = IR \), where \( I \) is the same current for all components in series, and \( R \) is the resistance of the component).

1. Evaluate the options:

• First option: “each bulb gets the full voltage from the battery” → Incorrect. In series, voltage is divided, not all components get the full voltage (that’s parallel circuits).
• Second option: “the voltage each bulb gets depends on how far away it is from the battery” → Incorrect. Voltage distribution in series depends on resistance, not distance from the battery.
• Third option: “each bulb gets part of the voltage from the battery” → Correct. In a series circuit, the total battery voltage is split (distributed) among the components, so each bulb (component) gets a portion of the total voltage.

Answer:

each bulb gets part of the voltage from the battery
