Understanding Parallel Circuits

What is a parallel circuit?

• A circuit with components in a triangle shape

• A circuit with components in a single loop

• A circuit with components on separate branches

• A circuit with no components

In a parallel circuit, what happens if one bulb is removed?

• The circuit stops working

• All bulbs go out

• The voltage increases

• The remaining bulbs stay lit

How is the potential difference (voltage) across each branch in a parallel circuit?

• It is different for each branch

• It is zero

• It is half of the cell's potential difference

• It is the same as the potential difference produced by the cell

How is the potential difference (voltage) across each bulb in a series circuit?

• it is the same as the battery

• it is random

• It is half

• It is split evenly across the bulbs

What is the unit of current?

• Amperes

• Ohms

• Volts

• Watts

What is the effect of adding more bulbs in parallel on their brightness?

• Their brightness stays the same

• They become dimmer

• They flicker

• They become brighter

What is the effect of adding more bulbs in series on their brightness?

• Their brightness stays the same

• They become dimmer

• They flicker

• They become brighter

What is the role of switches in a parallel circuit?

• To decrease voltage

• To control individual components

• To change the circuit shape

• To increase resistance

What happens to the current at a junction in a parallel circuit?

• It stops

• It splits and flows through each branch

• It reverses direction

• It doubles

How does the current behave in different branches of a parallel circuit?

• It is zero in all branches

• It is the same in all branches

• It varies depending on resistance

• It is maximum in all branches
