Understanding Series and Parallel Circuits

What are the four basic components of an electrical circuit?

• Battery, resistor, capacitor, and diode

• Source, transistor, wires, and switch

• Battery, light bulb, capacitor, and switch

• Source, light bulb, wires, and switch

In a series circuit, what happens when one bulb is removed?

• The other bulbs will continue to light

• The other bulbs will flicker

• The other bulbs will not light up

• The other bulbs will shine brighter

Why do the other bulbs in a parallel circuit remain lit if one bulb is removed?

• The voltage increases

• The circuit automatically repairs itself

• The current is redirected to other bulbs

• Each bulb has its own pathway

What materials are suggested for building a circuit in the hands-on activity?

• Cardboard, copper wire, and one battery

• Illustration board, aluminum foil, and two batteries

• Wooden board, electric tape, and three batteries

• Plastic board, copper tape, and one battery

What is a disadvantage of using a series circuit?

• The voltage is too high

• The current is too low

• If one bulb fails, all bulbs go out

• It requires more components

What is an advantage of using a parallel circuit?

• It is easier to repair

• It requires fewer wires

• Each component receives the same voltage

• It is cheaper to build

In a parallel circuit, what happens to the voltage across each bulb?

• It decreases

• It increases

• It remains the same

• It fluctuates

What is a key characteristic of a series circuit?

• Automatic voltage adjustment

• Variable resistance

• Single pathway for current

• Multiple pathways for current

Which type of circuit is more suitable for home lighting?

• Both are equally suitable

• Parallel circuit

• Series circuit

• Neither is suitable

What happens to the current in a series circuit if more cells are added?

• The current remains the same

• The current fluctuates

• The current decreases

• The current increases
