Voltage Divider Calculator
Calculate the output voltage (Vout) in voltage divider circuits for precise circuit design. Determine Vout based on resistor values and input voltage using the standard voltage divider formula.
Step 1: Circuit Specifications
Voltage Divider Formula
Vout = Vin × (R2 ÷ (R1 + R2))
A voltage divider reduces a higher voltage to a lower voltage using two resistors in series. It’s a fundamental circuit in electronics.
Step 2: Visualization & Options
About Voltage Dividers
Voltage dividers are used to create reference voltages, level shift signals, and bias active circuit elements. The output voltage depends on the ratio of R2 to the total resistance (R1 + R2).

Voltage Divider Formula
Vout = Vin × (R2 ÷ (R1 + R2))
Where:
• Vin = Input Voltage
• R1 = First resistor in series
• R2 = Second resistor in series
• Vout = Output voltage across R2
The current through the divider: I = Vin ÷ (R1 + R2)
