Topic 2a - circuits (4. parallel circuits)

Question 1

define a parallel circuit

Answer 1

components connected in parallel each have their own branch in a circuit connected to the + and - terminal of the supply. if you remove or disconnect one of them it will hardly effect any of the other components.

Question 2

Potential difference in parallel circuits

Answer 2

each branch in the circuit has the same potential difference as the power supply.

Question 3

current in parallel circuits

Answer 3

I1 = I2 + I3

Question 4

summary of series circuits 3 important rules

Answer 4

pd across each branch is same a the pd of the source pd
the current is split across the branches and the total current is the sum of the current of each branch
the total resistance of a parallel circuit is less than the smallest resistance of an individual circuit branch
