ELECTRIC CIRCUIT

What is an electric circuit?

• The particles that carry electric charge, typically electrons in metallic conductors.

• A device that provides the electrical potential difference (voltage) to drive the charge flow.

• A closed loop path that allows for the flow of electric current.

• The flow of electric charge through a conductor.

What are the two main requirements for an electric circuit?

• A closed conductive path and an energy source.

• An energy source and a charge carrier.

• A closed conductive path, an energy source, and a charge carrier.

• A closed conductive path and a charge carrier.

What is electric current?

• The rate at which electrical energy is transferred or consumed in a circuit.

• The opposition to the flow of electric current within a material.

• The electrical potential difference between two points in a circuit.

• The flow of electric charge through a conductor.

What is Ohm's Law?

• A fundamental law stating that the voltage across a conductor is directly proportional to the current through it and inversely proportional to its resistance (V = IR).

• A fundamental law stating that the resistance of a conductor is directly proportional to the voltage across it and inversely proportional to the current through it (R = V/I).

• A fundamental law stating that the power dissipated in a conductor is directly proportional to the voltage across it and inversely proportional to its resistance (P = V^2/R).
