Voltage Divider Calculator
About:
A voltage divider is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (V1). Voltage dividers are used to make signal level adjustments, for active device and amplifier bias, and for measuring voltages.
Formula: Vout = R2 ÷ (R1 + R2) × V1
