If a fourth bulb is added in parallel to the circuit, what happens to the total resistance?

• It increases

• It decreases

• It stays the same

• It becomes infinite

If the battery voltage is doubled in a parallel circuit, what happens to the current through each bulb?

• It is halved

• It is doubled

• It stays the same

• It becomes zero

What is a parallel circuit?

• A circuit where each resistor is connected to the battery along its own, individual path.

• A circuit where all resistors are connected in a single line.

• A circuit with only one resistor.

• A circuit that does not use a battery.

In a parallel circuit, if one bulb fails, what happens to the other bulbs?

• They stay on

• They all go out

• They flicker

• They get brighter

Which of the following best describes a parallel circuit?

• All components are in a single line

• Each component is on its own path

• Only one component is connected

• No components are connected

Which of the following best describes the flow of current in a parallel circuit?

• It flows through only one resistor

• It splits and flows through each resistor separately

• It reverses direction at each resistor

• It stops at each resistor

Which statement is true about resistance and current in a parallel circuit?

• Less resistance means more current

• More resistance means more current

• Resistance does not affect current

• Current is always the same in all paths
