## How it works

Interactive voltage divider calculator with circuit diagram preview, load resistance compensation, and standard E-series resistor pair finder.

Calculates unloaded and loaded voltage dividers (Vout = Vin * (R2 || RL) / (R1 + (R2 || RL))), current draw, and power dissipation. The target voltage mode scans E12, E24, and E96 series for optimal resistor pairs with lowest voltage error.

Uses standard electrical formulas for loaded and unloaded voltage dividers to calculate output voltage, current draw, and power dissipation. Scans E-series matrices to match target voltages.
