Current is the same through all
resistors
Total potential difference = sum of
the individual potential difference
Individual potential difference
directly proportional to the
individual resistance
Total resistance is greater than
greatest individual resistance
Potential difference is the same
through all resistors
Total Current = sum of the
individual current
Individual current inversely
proportional to the individual
resistance
Total resistance is less than least
individual resistance
Notice that parallel resistors combine in the same way that series
capacitors combine, and vice versa.
