What is a Diode Connected in Reverse Biased?
A diode connected in reverse biased is one in which the positive voltage of a
voltage source is connected
to the cathode of the diode and the negative or ground of the voltage source is connected to the anode
of the diode.
When a diode is connected in reverse biased, current does not flow through the circuit, as shown above.
If the diode is flipped around so that the positive voltage is supplied to the anode and negative voltage to the cathode, the diode is said to be forward biased. In a forward biased condition, the diode will conduct and current will flow through it.
One key characteristic of a diode is it is a one-way device. Current can only flow through a diode
when it is connected forward biased.
