Resistors
Voltage Divider Calculator
Calculate Vout of a two-resistor divider, plus current draw and power dissipation. Includes formulas and the standard E12 resistor value.
Vout
2.500 V
Vout = Vin × R2 / (R1 + R2)
Current draw
0.250 mA
P(R1)= 0.63 mW · P(R2)= 0.63 mW
Nearest E12 values — R1: 10 kΩ · R2: 10 kΩ
