What is the Voltage Divider Calculator?

The Voltage Divider Calculator helps students, engineers, and electronics enthusiasts determine the voltage drop across each resistor in a series circuit. By entering the series resistances and the input voltage, the tool calculates the voltage distributed across each resistor and ensures accurate analysis of the circuit. This is especially useful for designing circuits, measuring expected voltages, and preventing errors in electronics projects.

How to Use:

1. Enter Series Resistances (Ω): Input the resistances of each resistor in the series circuit, separated by commas (e.g., 10, 20, 30).
2. Enter Input Voltage (V): Input the total voltage applied across the series network.
3. Click “Calculate”: The calculator computes the voltage drop across each resistor using the voltage division principle.
4. Review Result: The output displays the entered resistances, input voltage, voltage drop across each resistor, and the total voltage to ensure it matches the input for verification.
