Calculates output voltage, current draw, and power dissipation for a resistive voltage divider. Given an input voltage Vin and two resistor values R1 (upper) and R2 (lower), computes Vout = Vin * R2 / (R1 + R2), divider current, individual resistor power dissipation, and the division ratio. Essential for biasing circuits, level shifting, ADC input scaling, and feedback networks. Use before trace_width to size traces for divider current, or chain from a power supply output to verify signal levels.
