Parallel circuit

Question 1

What is parallel circuits ?

Answer 1

Each component is separately connected to +ve and -ve of power supply ( except ammeters which is connected in series)

If you remove or disconnect any components, it’ll hardly affect the others

example = cars
switch everything on and off separately

Question 2

PD Is

Answer 2

same across all components ( full source PD)
individual bulbs connected in parallel = same brightness

Question 3

Current is

Answer 3

shared between branches
Total current = total current of separate components

Total current entering junction is equal to total current leaving

Two identical components connected in parallel = same current through them

Question 4

Total resistor is smaller than the resistor of the smallest of two resistors

Answer 4

another loop = current has more than 1 direction to go in

increase in current = decrease in total resistance of circuit
