Question

which option represents a typical voltage source? voltmeter wire battery insulator

Explanation:

To determine the typical voltage source, we analyze each option:

• A voltmeter is a measuring instrument, not a source.
• A wire is a conductor for current, not a source.
• A battery is a device that stores and provides electrical energy (voltage), acting as a voltage source.
• An insulator resists current flow, not a source.

Answer:

battery
