What is a Diode Connected in Forward Biased?

A diode connected in forward biased is one in which the positive voltage of a voltage source is connected to the anode 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 forward biased, current flows through the diode and it conducts.

If the diode is flipped around so that the positive voltage is supplied to the cathode and negative voltage to the anode, the diode is said to be reverse biased. In a reverse biased condition, the diode will not conduct and current will not flow.

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.
