When the polarity of the battery is such that electrons are allowed to flow through the diode, the diode is said to be forward-biased. Conversely, when the battery is “backward” and the diode blocks current, the diode is said to be reverse-biased.

The Electronics Club ... Diodes allow electricity to flow in only one direction. The arrow of the circuit symbol shows the direction in which the current can flow. ... The forward voltage drop of a diode is almost constant whatever the current passing through the diode so they have a very steep characteristic (current-voltage graph).

Before we discuss any specific types of special diodes, we need to show how voltage across a diode and current flow through a diode are related. The following graph shows voltage on the x-axis and current flow on the y-axis.

When a voltage is applied in the reverse direction we say that the diode is reverse biased. When the diode is reverse biased, the potential barrier builds up across the junction and opposes current flow through the diode.

When the diode is reverse biased, the potential barrier builds up across the junction and opposes current flow through the diode. The greater the applied reverse voltage, the larger the barrier. When reverse biased, only a very small leakage current flows.

To equalize current flow through a pair of chokes supplying a d-c load from a d-c source, ... 4. The rising portion of the current i.sub.S occurs when thesupply 10 is connected through the conductive switch 11 to the choke; the dropping portion i.sub.D is the current which flows due to the presence of the free-wheeling diode 12,

Conventional current flow through a diode. ... For diodes the characteristic curve is called an I/V curve because it shows the relationship between the voltage applied between the anode and cathode, and the resulting current flowing through the diode. A typical I/V characteristic is shown in figure 3.1.1e.
