Parallel Circuits Flashcards
Electricity (11 cards)
What is the connection configuration of components in parallel circuits?
Each component is connected separately to the +ve and -ve of the supply
Except ammeters, which are usually connected in series.
What happens to other components if one is removed in a parallel circuit?
It will hardly affect the others at all.
Why is the parallel connection configuration used in everyday applications?
It allows for independent control of each component.
What is the potential difference across all components in a parallel circuit?
The same across all components: V1 = V2 = …
What is the effect of connecting identical bulbs in parallel?
All bulbs will be at the same brightness.
How is the total current in a parallel circuit calculated?
I total = I1 + I2 + …
What must be true about the current at junctions in a parallel circuit?
The total current going into a junction must equal the total current leaving.
If two identical components are connected in parallel, what can be said about the current?
The same current will flow through each component.
What happens to the total resistance when adding a resistor in parallel?
The total resistance is less than the resistance of the smallest of the two resistors.
What is the effect of adding another loop in a parallel circuit?
It increases the total current that can flow around the circuit.
What relationship is used to explain the decrease in total resistance when current increases?
Using V = IR.
