What does conservation of charge affect?
Current
Total current into a junction= … (parallel)
Total current out of a junction
What’s the current in series?
Same everywhere
What’s the potential difference in series?
Sum of p.d.s= emf
What’s potential difference in parallel?
Same across each branch
What does the conversation of energy affect?
Potential difference
What’s resistance in series?
Rtotal= R1+R2…
What’s resistance in parallel?
1/Rtotal= 1/R1 +1/R2…
