### resistance - How do I calculate the resistor value for a …

Say you have 2 resistors in series in your circuit, 10 ohm and 20 ohm. That''s a total of 30 ohm, so the current will be 3v / 30 ohm = 100 mA. If you calculate the voltages over your resistors you get 100 mA * 10 ohm = 1 V, and 100 mA * 20 ohm = 2V. 1V + 2V

### Voltage Drop Calculation | Electrical4U

Voltage drop means the reduction in voltage or voltage loss. Due to the presence of the impedance or passive elements, there will be some loss in voltage as the current moves through the circuit. That is, the energy supplied from the voltage source will get reduced
