What is necessary to allow charge flow between two charged plates?

• A magnetic field

• A wire or conductor

• A resistor

• A capacitor

What happens when a closed conducting loop is formed in a circuit?

• The wires heat up

• The light bulb lights up

• The battery discharges

• The circuit becomes open

What is the origin of the word 'circuit'?

• Greek word for 'circle'

• Latin word 'circum' meaning 'to go around'

• French word for 'loop'

• German word for 'path'

What part of the light bulb is responsible for producing light?

• The filament

• The ribbed side

• The base

• The glass bulb

What is the significance of the filament in a light bulb?

• It produces light when charge flows through it

• It supports the glass bulb

• It connects the ribbed side to the base

• It provides insulation

Which of the following is NOT a requirement for an electric circuit?

• A source of energy

• A magnetic field

• A difference in electric potential

• A closed conducting pathway

What is the role of an energy source in an electric circuit?

• To increase the resistance

• To maintain a constant electric potential difference

• To decrease the current

• To provide insulation

What happens if there is a break in the closed conducting pathway?

• The circuit continues to function

• The flow of charge ceases

• The light bulb becomes brighter

• The battery charges

What is the purpose of a charge pump in an electric circuit?

• To increase the voltage

• To maintain a constant electric potential difference

• To decrease the resistance

• To provide a magnetic field

What is the result of using a paper clip in a circuit experiment?

• It decreases the voltage

• It increases the resistance

• It completes the circuit

• It interrupts the circuit
