text: When a diode is reverse-biased, it acts as an insulator and does not permit current to flow.
text: (b) Current flow is prohibited; the diode is reversed biased.
text: We have also seen above that the diode is two terminal non-linear device whose I-V characteristic are polarity dependent as depending upon the polarity of the applied voltage, V D the diode is either Forward Biased, V D > 0 or Reverse Biased, V D < 0.
text: The same diode in Figure #2 could be considered Reverse Biased, when the switch is off and the alarm is activated, because it is allowing the alarm to power only one bulb and is blocking the current from back feeding to the other components in the circuit.
text: Likewise, when the cathode voltage is more positive than the anode, the diode is said to be reverse-biased.
text: A diode is said to be reverse-biased when the battery’s voltage is dropped completely.
text: Conversely, when the battery is “backward” and the diode blocks current, the diode is said to be reverse-biased.
text: When voltage is applied across a diode in such a way that the diode prohibits current, the diode is said to be reverse-biased.
text: The diode doesn't conduct current while the switch is closed because it is reverse-biased by the battery voltage, so it doesn't interfere with normal operation of the circuit.
text: A diode is reverse-biased when the positive (red) test lead is on the cathode and the negative (black) test lead is on the anode.
text: Zener Diode Operation Please take note of the Zener diode’s orientation in the above circuit: the diode is reverse-biased, and intentionally so.
text: If a diode is reverse-biased, the voltage at the cathode is comparatively higher than at the anode.
text: In positive series clipper, during the positive cycle of the input, the diode is reverse-biased so the voltage at the output is zero.
text: During the positive half-cycle of the input, diode is reverse-biased so the output voltage is equal to the sum of input voltage and capacitor voltage (considering the capacitor is initially charged).
text: But, in case of wrong connection, the diode is reverse-biased and that doesn’t allow any current to flow to the load.
text: For rectifier applications, peak inverse voltage (PIV) or peak reverse voltage (PRV) is the maximum value of reverse voltage which occurs at the peak of the input cycle when the diode is reverse-biased.
text: Whereas, if the diode is reversed biased, it acts like an open switch as shown in the figure below.
