Exploring Electric Circuits and Their Essential Requirements

What is required besides two oppositely charged plates to establish an electric circuit?

• A switch

• A battery

• A wire or conductor

• A light bulb

What must be true for a setup to be considered an electric circuit?

• It must use alternating current

• It must operate at high voltage

• It must have a closed conducting loop

• It must include at least one light bulb

What happens when a closed conducting loop is completed in an electric circuit?

• No change is observed

• The light bulb remains off

• The light bulb lights up

• The battery drains immediately

What is the primary function of a battery in an electric circuit?

• To maintain a constant electric potential difference

• To increase resistance

• To reduce the electric potential

• To act as a switch

What demonstrates that charge is flowing through a wire in an electric circuit?

• A compass needle deflects

• The wire heats up

• The wire vibrates

• The wire changes color

What is the role of the filament inside a light bulb?

• To emit light when heated by charge flow

• To store extra charge

• To insulate the bulb

• To connect the rib side to the base

Why is it important for the light bulb to be part of the closed conducting loop in an experiment?

• To ensure the bulb emits sound

• To make the setup look more complex

• To ensure the bulb lights up

• To increase the circuit's resistance

Which connection will not light up the bulb in an electric circuit?

• Connecting both wires to the rib side

• Connecting one wire to the base and leaving one unconnected

• Connecting both wires to the base

• Connecting one wire to the rib side and one to the base

What causes a light bulb to not light up when a paper wad is used in the circuit?

• The paper wad absorbs all the light

• The paper wad is an insulator and interrupts the conducting pathway

• The paper wad conducts too much electricity

• The paper wad reflects light away from the bulb

What happens if there is a break in the conducting pathway of an electric circuit?

• The battery will charge itself

• The flow of charge ceases

• The light bulb will flicker but remain lit

• The circuit will still function but less efficiently
