Voltage Drop Calculator
Calculate voltage drop, load voltage, I²R loss, conductor area, and current density for DC, single-phase, or three-phase circuits.
Open calculator →Electrical Engineering Calculators
Focused circuit and electrical-design calculators for voltage, current, power, conductor sizing, and three-phase systems.
Every calculator below is a focused interface over an existing Neutron STEM Lab engineering engine. Use the standalone route for a fast result, then move into the linked workbench when the calculation becomes part of a larger design or simulation.
Wire Size Calculator
Screen 32 AWG through 4/0 AWG against voltage-drop and current-density limits using the EE Design Workbench engine.
Open calculator →Three-Phase Power Calculator
Calculate kVA, kW, kVAR, delivered power, phase angle, and estimated losses from line voltage, current, power factor, and efficiency.
Open calculator →Ohm’s Law Calculator
Solve for voltage, current, resistance, power, and conductance for an ideal resistive element.
Open calculator →Voltage Divider Calculator
Calculate unloaded and loaded divider output voltage, source current, load current, and loading error.
Open calculator →Continue into the full engineering workbenches
The standalone calculators are intentionally narrow. These linked workbenches use the same underlying engines while adding broader analysis, simulation, comparison, and design workflows.
Electrical Design
Size and compare conductors, calculate voltage drop and cable loss, and solve DC, single-phase, and balanced three-phase power without jumping between reference charts.
Introductory Circuits
Learn DC and introductory AC circuit analysis through Ohm’s law, power, resistor networks, Kirchhoff’s laws, equivalent circuits, first-order transients, resonance, filters, and resistor color codes.
