What is Series-Parallel Resistance?
In electronic circuits, resistors can be connected in different arrangements to achieve specific resistance values. The two fundamental ways to connect resistors are in series and in parallel.
Understanding how resistors combine in these configurations is essential for circuit design, troubleshooting, and analysis in various electronic applications.
Series Connection
In a series connection, resistors are connected end-to-end in a single path. Current flowing through one resistor must flow through all others. The total resistance increases with each added resistor.
Parallel Connection
In a parallel connection, resistors provide multiple paths for current flow. The total resistance is always less than the smallest individual resistor value, as parallel paths reduce overall resistance.
