Series/parallel Flashcards
To learn all facts about electrical factors in series and parallel circuits
1
Q
What happens to p.d in series?
A
P.d is shared
2
Q
What happens to current in series
A
Same everywhere
3
Q
What happens to resistance in series?
A
Adds up
4
Q
What happens to p d in parallel?
A
Same across all branches
5
Q
What happens to current in series circuit?
A
Shared between branches
6
Q
What happens to resistance in parallel?
A
Resistance decrease
Because If there are more branches more charge flows round circuit in a certain time (higher net current)
+ P.D STAYS THE SAME
-The equation: resistance=P.d÷current SHOWS INCREASING CURRENT THROUGH CIRCUIT AND KEEPING P.D FIXED MEANS NET RESISTANCE DECREASES.
