Voltage divider calculator lets you calculate the output potential dropped across the resistor. VSWR Calculator. 2. Collapse. Voltage divider calculator. The input voltage is distributed among the resistors or components of the voltage divider circuit. 555 Astable Calculator; 555 Monostable Calculator; Reference. It's output voltage is a fixed fraction of its input voltage. The two impedance voltage divider is used often to supply a voltage different from that of an available AC signal source. Usefull if you need to enter V out. Copyright © 1995-2020, Digi-Key Electronics. A law is relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. The circuit divides the source voltage into two parts. Digi-Key’s tools are uniquely paired with access to the world’s largest selection of electronic components to help you meet your design challenges head-on. So let's solve this using the voltage divider expression. A voltage divider is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (V1). This voltage divider calculator can be used to calculate the resistive voltage drop across two, three, four or five resistors in series.
