Voltage Divider
Solve Vout, current, and power for a two-resistor divider.
Vout = Vin × R2 / (R1 + R2)
2.5 V
Vout
250 µA
Current
1.25 mW
Power (R1+R2)
Vout is the voltage at the junction between R1 and R2, measured to ground. These figures assume a high-impedance load — if your load draws meaningful current, put it in parallel with R2 and recompute.
