potential dividers Flashcards
1
Q
pd across ammeters
A
0
so no effect on current flowing through
2
Q
current across voltmeters
A
0
really high resistance
3
Q
kirchoffs pd rule
A
pd same across each branch in parallel
4
Q
kirchoffs current rule
A
current into junction same as current out
5
Q
ratio of resistances is equal to
A
ratio of pds
6
Q
when adding a component in parallel
A
the resistance a d therefore share of pd changes b\
7
Q
A
