series and parallel circuit rules Flashcards
1
Q
for any closed loop around a circuit.
sum of pd across components
A
equals total emf supplied
2
Q
1 volt equals
A
1 joule of energy per couloumb of charge
3
Q
sum of pd across compents = total emf supplied shows
A
conservation of energy
4
Q
current in a series circuit
A
equal everywhere
5
Q
current in a paralell circuit
A
current splits at juctions
6
Q
1 amp equals
A
1 coloumb of charge per second
7
Q
finding resistor rule in series
A
use pd rule.
since V=IR
divide each term by current
8
Q
finding resistor rule in parallel
A
use current rule
use I=V/R
divide each term by pd
