Embed This Calculator

Put the full three-mode voltage drop calculator on your own site, blog or forum resource page — free, no signup, no tracking added beyond our standard analytics. Paste this snippet anywhere HTML is allowed:

The simulator widget

For forum answers and client-facing pages, the visual simulator — sliders, color-changing wire, dimming bulb — embeds the same way:
