Did you know?
WebA regular small zener diode is often rated for 400mW. At this point you know the zener voltage and its maximum power, therefore you can calculate the maximum current through the diode: I Z, m a x = P m a x V Z. WebTo solve the circuit graphically with a reversed diode, you draw the diode curve flipped around the current axis (draw the rising part of the diode curve is to the left of the current axis). In this case you will notice the diode line and the …
WebCalculate the power dissipated by the 5-volt zener diode for the following values of motor current (assume the battery voltage remains constant at 12 volts): I motor = 20 mA ; P zener =. I motor = 50 mA ; P zener =. I motor = 90 mA ; P zener =. I motor = 120 mA ; P zener =. I motor = 150 mA ; P zener =. WebApr 24, 2024 · Connect two of the wires to the Zener’s anode.
