What Is a Resistor Network?

A resistor network is a group of resistors connected together in different ways to control voltage, current, and resistance within a circuit.

Common resistor network types include:

• Series circuits
• Parallel circuits
• Series-parallel combinations
• Ladder networks
• Balanced resistor systems

These networks are found in almost every electronic device.
