6) Parallel Circuits:

What is unique about components in a parallel circuit?

Each component is connected separately to the power supply, allowing independent operation.

What happens if one component in a parallel circuit is disconnected?

The other components continue working unaffected.

How is potential difference distributed in a parallel circuit?

It is the same across all components and equal to the source potential difference.

Why do identical bulbs in parallel have the same brightness

Each bulb gets the full source potential difference.

How is current managed in parallel circuits?

Total current is split among the branches; it is the sum of currents in each branch.

What must be true at any junction in a parallel circuit?

The current entering a junction equals the current leaving it.

What happens to total resistance when more resistors are added in parallel?

Total resistance decreases.

Why does adding a resistor in parallel lower total resistance?

Each added resistor provides a new path for current, increasing total current and reducing resistance.

How does V = IR apply to a parallel circuit?

As current increases with additional branches, total resistance must decrease to keep V constant.
