Free web calculators for energy, solar, battery runtime, UPS runtime, EV charging cost, voltage drop, wire-size estimates, Ohm's law, voltage divider, and resistor calculations. Each calculator shows formulas, assumptions, limitations, and result logic so users can understand the estimate instead of relying on a black box.
