Resistor voltage drop calculator
To calculate the resistor needed for a simple LED circuit simply take the voltage drop away from the source voltage then apply Ohms Law. Find the current through each resistor.
Voltage Divider Calculator From Ab Electronics Uk Voltage Divider Divider Math
It is effortless and the ohm law is the best tool for it because we have the resistance and current of each resistor so we can find the corresponding voltage easily.
