This tool calculates the current through a voltage divider network consisting of any number of resistors.
- Voltage (Vin)
- Resistance (R1, R2, R3, etc.)
Using Ohm’s Law, the total current is given by
Itotal = Vin/(R1+R2+R3+…)
If R1= 1 ohm, R2 = 1.75 ohm, R3 = 2.25 ohm and Vin = 5 Volt, the total current is 1 Amp.
Use these calculators to find the voltage drop across each resistor when there are:
