cara menghitung nilai R pada dioda zener

How to Determine the Resistor Value on a Zener Diode to Reduce Voltage Determining the R value is crucial to achieving a stable output voltage without dropping or overheating the resistor. We also need to calculate the resistor's power rating. The formula used still uses Ohm's law: V = I x R And to determine the resistor's power, we use the power formula: P = V x I Hopefully this is helpful #howtoreducevoltage #Rvalueonzenervoltagereducer #stepdown
