Calculator

Power

Calculate electrical power from voltage and current.

Safety first, always.

ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.

Visual schematic

Load power path

Voltage across the load and current through it set the heat and power demand.

TP1: voltage

TP2: current path

TP3: load heat

Diagrams are simplified learning models for low-voltage electronics. They are not wiring instructions for mains, switchboards, fixed wiring, or legal electrical work.

Formula notes

P = V x I

Check component wattage and leave margin. Heat is usually where the lesson gets real.

1. Estimate

Load the example or enter a real low-voltage learning value.

2. Visualise

Use the diagram to connect the formula to current path, timing, frequency, or energy flow.

3. Verify safely

Build only suitable low-voltage circuits and confirm with a meter before scaling up.
