Source sentences:
text: The forward resistance must be very small in few ohms while backward resistance must be very high in the range of mega ohms.
text: If forward resistance is very high the diode is open circuited and if backward resistance is very small diode will be short circuited.
text: When the diode is forward-biased, the resistance of the diode is so small.
text: Thus, practically speaking, every diode is seen to offer a small resistance when forward biased, and a considerable resistance when reverse biased.
text: This resistance is small enough to allow a large current to flow, but high enough so that the heat it dissipates due to the high current flow (remember, P = I²R) is sufficient to melt or even vaporize the semiconductor material of which the diode is made.
text: The forward resistance is very small because of its tunneling effect.
