Resistors in Parallel Formulas
Resistors in parallel are typically connected in parallel between two nodes, for example, between node b and e in
the figure above, one end of all three resistors are connected to node b and all other ends connected to node e. Their equivalent
resistance R is :
Add more resistors in parallel will decrease the resistance R in combination. The potential drop V across each resistor in a parallel
combination is the same. The total current is equal to the sum of all parallel branch currents.
For resistors in series as below:
Their equivalent resistance R is:
Add more resistors in series will increase the resistance R in combination. The total potential drop V across the combination is equal to the sum of
each resistance potential drops. The current through each resistance is the same.
