Flashcards in Parallel Circuits Deck (7):
1

Describe Parallel circuits (3)

1) Each component is separately connected to the =ve and -ve of the supply
2) If you remove/disconnect one of them, it will hardly affect the others
3) How most things are connected

2

Describe potential difference in Parallel circuits

1)) All components get the full source P.D, so the voltage is the same across all components
V₁ = V₂ = V₃
2) This means that identical bulbs connected in parallel will all be at the same brightness

3

Describe current in Parallel circuits

1) The total current flowing around the circuit is equal to the total of all the currents through the separate components: A = A₁ + A₂...
2) There are junctions where the current either splits or rejoins. The total current going into a junction has to equal the current leaving it

4

Describe ammeters in all circuits

Always connected in series

5

Describe voltmeters in all circuits

Always connected in parallel with a component

6

Why are parallel circuits used in cars?

1) Everything can be turned on and off separately
2) Everything gets the full, voltage from the battery

7

What is the disadvantage of using parallel circuits in cars?

If lots of things are o the lights might dim because the battery can't provide full voltage under heavy load.
