TO2_DC Circuit

What is the fundamental relationship between voltage, current, and resistance in electrical circuits known as?

• Ohm's Law

• Newton's Law

• Coulomb's Law

• Faraday's Law

What does Ohm's Law state about the relationship between current and voltage in a circuit with fixed resistance?

• Current is directly proportional to voltage

• Current is inversely proportional to voltage

• Current is equal to voltage

• Current is independent of voltage

What is the role of voltage in a DC circuit?

• It acts as the force that pushes electrons through a conductor

• It measures the opposition to current flow

• It is the flow of charge around the circuit

• It is the resistance encountered by electrons

In a DC circuit, what is the unit of measurement for electrical current?
