Series vs Parallel Circuits

What is an electric circuit?

• A pathway through which an electric current flows.

• A device that converts electricity into other forms of energy.

• A material that stops the flow of electric current.

• A system that generates electricity.

Which of the following is NOT a component of a simple electric circuit?

• Battery

• Conductor

• Insulator

• Load or Resistor

In a series circuit, what happens if one electrical component fails?

• Only that specific component stops working, while others continue.

• The entire circuit stops working.

• The current flow increases in the remaining components.

• The brightness of other bulbs increases.

In a parallel circuit, if one light bulb breaks or burns out, what happens to the other bulbs?

• All other bulbs will also go out.

• The other bulbs will remain lit.

• The other bulbs will become brighter.

• The current flow to the other bulbs will stop.

• Yes

• No

What happens in a parallel circuit if one device or appliance stops working?

• All other devices also stop working.

• The other devices continue to work.

• The circuit becomes overloaded.

• The current flow increases in the remaining devices.

Which of the following is a disadvantage of a parallel circuit?

• Each component is independent.

• Cells connected in parallel last longer.

• More connecting wires are required.

• All electrical devices have the same brightness.

How many pathways are there for current to flow in a series circuit?

• Two or more pathways.

• Only one pathway.

• Multiple independent pathways.

• No specific number of pathways.

What does the symbol with a long line and a short line, separated by a gap, represent in a schematic circuit diagram?

• A battery

• A light bulb

• A cell

• A closed switch
