Circuit Basics

What is a simple circuit?

• A type of geometric shape

• A single path for the flow of water

• A complex network of wires and components

• A single continuous path for the flow of electric current.

What are the basic components of a simple circuit?

• Power source, switch, conductive wires

• Generator, load, conductive wires

• Food source, load, conductive wires

• Water source, load, conductive wires

What is the role of a battery in a simple circuit?

• To provide electrical energy to power the circuit.

• To generate light for the circuit

• To provide mechanical energy to the circuit

• To cool down the circuit

Explain the concept of open and closed circuits.

• An open circuit allows the flow of electricity, while a closed circuit does not.

• An open circuit is always safe to touch, while a closed circuit is dangerous.

• An open circuit only works with batteries, while a closed circuit works with both batteries and generators.

• An open circuit does not allow the flow of electricity, while a closed circuit does.

How does a switch work in a simple circuit?

• By opening or closing the circuit

• By adding more batteries to the circuit

• By increasing the resistance in the circuit

• By changing the color of the wires

What is the purpose of a resistor in a simple circuit?

• To store energy and release it when needed in the circuit.

• To limit the flow of current and control the amount of voltage in the circuit.

• To generate heat and light in the circuit.

• To increase the flow of current and maximize the amount of voltage in the circuit.

Describe the flow of electrons in a simple circuit.

• Electrons flow in a random direction within the circuit.

• Electrons flow from the positive terminal to the negative terminal of the power source.

• Electrons flow from the negative terminal to the positive terminal of the power source.

• Electrons flow from the positive terminal to the negative terminal of the load.

Explain the concept of voltage in a simple circuit.

• Voltage is the measure of the speed of electrons in a circuit.

• Voltage is the measure of electric potential difference between two points in a circuit.

• Voltage is the measure of the resistance in a circuit.

• Voltage is the measure of the amount of current flowing through a circuit.

How does a light bulb function in a simple circuit?

• The flow of electricity through its filament heats up and produces light.

• The light bulb absorbs electricity and emits light

• The light bulb reflects sunlight to produce light

• The light bulb uses magnets to create light

Current that flows in 1 direction and is usually produced by batteries.

• AC

• DC

• Magnetism

• CC
