Changing Resistance In Series/parallel Flashcards
To know what happens to the electrical factors when a the resistance of a component changes
1
Q
Series- what happens if the resistance of a component increases.
A
Takes a bigger share of the total p.d BECAUSE MORE ENERGY IS TRANSFEERED FROM THE CHARGE WHEN MOVING THROUGH A LARGE RESISTANCE.
(IN SERIES YHE P.D ACROSS ALL COMPONANTS WILL CHANGE. THE NET RESISTANCE WILL ALSO CHANGE THEREFORE THE CURRENT WILL CHANGE THROUGH THE CONPONANTS ASWELL).
2
Q
Parallel: what happens if the resistance of the one component changes?
A
If resistance increases in one component then current through THAT BRANCH will change but current + p.d will stay the same through other branches will stay the same.
