to determine the comparison of resistance value of both forward and reverse diode . The more the resistance the lower the current , the lower the resistance the higher the current . When reverse bias , the resistance is high and it acts in open circuit and the reverse current is very small that can be neglected . When forward bias , the resistance is low and it acts as short circuit and the forward current is increasing as the voltage supply is higher .
resistance created by a fluid to forward motion. The resistance met by a swimmer in their forward progress caused by the water is passive drag;
when a car is speeding up how does the forward force and air resistance compare
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
gravity holds you down wings + forward motion = lift thrust = forward motion air resistance = resistance to forward motion thin air at altitude is easier and cheaper to get through
Forward Resistance:def: It is resistance offered by diode to the forward bias is known as forward resistance.This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types :1. DC FORWARD RESISTANCE.2. AC FORWARD RESISTANCE.1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode to the resulting DC current through it.2. AC forward resistance: It is the opposition offered by the diode to the changing current. It is measured by the ratio of change in voltage across diodes to the resulting change in current through diode. The AC forward resistance is more significant as the diodes are generally used with alternating voltage.Reverse Resistance:def: The resistance offered by the diode to the reverse bias is known as Reverse Resistance. It can be DC reverse resistance or AC reverse resistance depending upon whether the reverse bias is direct or changing voltage. Idealy the reverse resistance of a diode is infinte however in practice the reverse resistance is not infinite because for any value of reverse bias, there does exist a small leakage current. It may be emphasized their that reverse resistance is very large compared to the forward resistance.These Definitions are from PRINCIPLES OF ELECTRONICS by V.K MEHTA and ROHIT MEHTA
ln reverse biase high resistance and in forward biase very low resistance
Air resistance and friction.
two forces that can stop the forward motion are, air resistance and friction.
In most fish, the tail provides forward thrust. However, I have seen certain fish use their pectoral fins to provide sustained forward thrust.
Wind resistance is a specific example of air resistance. Wind resistance would be a resistance to motion cause by a wind, for example when you try walking forward on a very windy day it is hard, that force preventing you from walking is wind resistance.
By lowering the automobile's wind resistance to its forward motion
