How To Calculate Voltage With Current And Resistance

How To Calculate Voltage With Current And Resistance. The voltage though may look huge, practically its found that due to maximum current restricted @ 35ma, the voltage drops drastically when a load is connected here. However since for an led even this output may be potentially harmful, an addition of a resistor becomes imperative.
