series and parallel circuits Flashcards
Why are parallel circuits more suitable for domestic lighting than series circuits?
In a parallel circuit, each light works independently. If one bulb breaks, the others stay on.
consistent brightness - in paralell all lights recieve the same voltage = same brightness ( in sereis voltage is divided)
individual control - in parallel circuit each light can be controlled individually
How does adding more components in series affect the current?
The total resistance increases, reducing the current in the circuit.
What happens to voltage in a parallel circuit?
Each branch receives the same voltage as the power supply.
What happens to current at a junction in a parallel circuit?
The total current splits between branches and is conserved at the junction.
What is a series circuit?
A circuit where all components are connected in a single loop, so the same current flows through each component.
What is a parallel circuit?
A circuit where components are connected on separate branches, so the current splits between them.
