What is a series circuit?

• A circuit with independent loops for current flow

• A circuit with all components connected in a single loop

• A circuit with multiple paths for current flow

• A circuit with no current flow

What is a parallel circuit?

• A circuit with all components connected in a single loop

• A circuit with multiple paths for current flow

• A circuit with independent loops for current flow

• A circuit with no current flow

What happens to the brightness of the first bulb in a series circuit when another bulb is added?

• It remains the same

• It becomes brighter

• It goes out

• It becomes dimmer

What happens to the brightness of the first bulb in a parallel circuit when another bulb is added?

• It becomes dimmer

• It remains the same

• It goes out

What happens when one bulb in a series circuit is burnt out?

• The brightness increases

• Only the burnt out bulb goes out

• The circuit stops working

• All bulbs go out

What happens when one bulb in a parallel circuit is burnt out?

• All bulbs go out

• Only the burnt out bulb goes out

• The brightness increases

• The circuit stops working

Why are home appliances connected in parallel circuits?

• To make the bulbs brighter

• To ensure the circuit stops working

• To have independent loops for current flow

• To make the bulbs dimmer

What is the disadvantage of a series circuit?

• A break in any part of the circuit stops the flow of current in the entire circuit

• The brightness of the bulbs remains the same

• The current in one loop affects the current in another loop

• The circuit becomes brighter with more bulbs

What is the advantage of a parallel circuit?

• The current in one loop affects the current in another loop

• The circuit becomes brighter with more bulbs

• The brightness of the bulbs remains the same

• A break in any part of the circuit stops the flow of current in the entire circuit

Why did only one bulb of the chandelier go out while all the bulbs of the decoration lights stopped working?

• The chandelier is connected in a series circuit

• The decoration lights are connected in a series circuit

• The decoration lights are connected in a parallel circuit

• The chandelier is connected in a parallel circuit
