Q: What is voltage measured in?

Volts (V) — Voltage is the potential difference measured in volts.

Q: Voltage is also known as:

Potential Difference — Voltage represents the potential energy difference between two points.

Q: Which of the following is a unit of voltage?

Volt — The Volt (V) is the standard unit for measuring electrical potential difference.

Q: In a simple circuit, voltage is provided by:

Power Source (e.g., battery) — A power source, like a battery, provides the voltage to drive the current.

Q: If a circuit has a voltage of 12V and a current of 2A, what is the resistance (using Ohm's Law: V=IR)?

6 Ohms — R = V/I = 12V/2A = 6 Ohms.

Q: Voltage causes what to flow in a circuit?

Current — Voltage is the driving force that pushes the current to flow.

Q: Which component *consumes* voltage in a circuit?

Resistor — A resistor drops (or uses) voltage due to its opposition to current flow.

Q: What happens to the voltage in a series circuit?

The voltage divides across the components. — Voltage divides across components in a series circuit based on their resistance.

Q: What does a voltmeter measure?

Voltage — A voltmeter is specifically designed to measure the electrical potential difference.

Q: In a parallel circuit, what is constant across all components?

Voltage — In a parallel circuit, the voltage is the same across each branch.
