What is the Node Voltage Calculator?

The Node Voltage Calculator helps engineers, students, and electronics enthusiasts analyze electrical circuits using the node voltage method. By entering the resistances and current sources, the tool calculates the voltages at key nodes in the circuit relative to the reference ground node. This allows users to efficiently understand voltage distribution in a circuit, aiding in design, analysis, and troubleshooting of electrical networks.

How to Use:

1. Enter Resistances (R₁, R₂, R₃) in Ohms (Ω): Input the values of the resistors connected to each node.
2. Enter Current Sources (I₁, I₂) in Amperes (A): Input the currents injected into the nodes.
3. Click “Calculate”: The tool computes the voltages at the nodes using the node voltage method.
4. Review Result: The output displays the entered resistances and currents, calculated node voltages V₁ and V₂ in Volts (V), and notes that the reference ground node is assumed to be at 0 V.
