Question

1. a voltmeter connected across, or in parallel with, a component in an electrical circuit will read the value of voltage applied to that specific component. which of the following best describes what this value is called?

total voltage

voltage drop

voltage divider

voltage adder

Explanation:

Analyze the question prompt

The question asks for the term that best describes the voltage value measured across a specific component in an electrical circuit.

Define the options

• Total voltage: The overall potential difference supplied to the entire circuit.
• Voltage drop: The reduction in electrical potential as current passes through a passive component.
• Voltage divider: A simple linear circuit that produces an output voltage that is a fraction of its input voltage.
• Voltage adder: An active circuit (often using op-amps) that sums multiple input voltages.

Match measurement to term

A voltmeter connected in parallel with a single component measures the difference in electrical potential between the two ends of that component. This potential difference represents the energy consumed per unit charge by the component, which is defined as the voltage drop across it.

Answer:

• Total voltage
• Voltage drop (Correct answer)
• Voltage divider
• Voltage adder
