Electrical Circuits

What is an electrical circuit?

• A closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

• A device that stores electrical energy for later use.

• A type of electrical component that regulates voltage.

• A method of generating electricity using solar panels.

What is a parallel circuit?

• A type of circuit where components are connected in a single path.

• A type of electrical circuit where components are connected across common points, providing multiple pathways for current to flow.

• A circuit that only allows current to flow in one direction.

• A circuit that has no resistance and allows infinite current to flow.

What is a switch in an electrical circuit?

• A device that can open or close a circuit, controlling the flow of current.

• A component that stores electrical energy for later use.

• A type of resistor that limits the flow of current.

• A tool used to measure voltage in a circuit.

What happens if one component fails in a series circuit?

• The entire circuit continues to function normally.

• Only the failed component stops working, while others remain operational.

• The entire circuit is interrupted, and all components stop functioning.

• The circuit automatically repairs itself and continues to work.

What is a complete circuit?

• A closed loop that allows current to flow uninterrupted from the power source, through the load, and back to the power source.

• A path that only allows current to flow in one direction.

• An open loop that prevents current from flowing.

• A circuit that has multiple power sources connected in series.

What is Ohm's Law?

• Ohm's Law states that the current (I) through a conductor is directly proportional to the voltage (V) and inversely proportional to the resistance (R): V = I × R.

• Ohm's Law states that the voltage (V) across a conductor is equal to the current (I) multiplied by the resistance (R): V = R × I.

• Ohm's Law states that the resistance (R) in a circuit is equal to the voltage (V) divided by the current (I): R = V / I.

• Ohm's Law states that the current (I) through a conductor is equal to the voltage (V) divided by the resistance (R): I = V / R.

What is an insulator?

• A material that allows electric current to flow freely, such as copper.

• A material that resists the flow of electric current, such as rubber or glass.

• A device that stores electric charge, like a capacitor.

• A type of circuit that uses minimal resistance.

What is a conductor?

• A material that allows electric current to flow easily, such as copper or aluminum.

• A material that prevents electric current from flowing.

• A type of electrical device used to store energy.

• A substance that can only conduct heat, not electricity.

What is the role of a battery in a circuit?

• A battery serves as the power source that provides the electrical energy needed to drive the current through the circuit.

• A battery acts as a resistor to limit the current flow in the circuit.

• A battery is used to store excess energy generated by the circuit.

• A battery functions as a switch to control the flow of electricity.

What is a load in an electrical circuit?

• A component that generates electrical energy

• A component that consumes electrical energy, such as a light bulb or resistor

• A type of electrical current

• A device that measures voltage
