AC forward resistance refers to the effective resistance experienced by an alternating current (AC) signal as it passes through a diode in the forward-bias direction. It is influenced by the diode's intrinsic resistance, as well as the capacitance and inductance of the diode. The AC forward resistance can impact the efficiency and performance of the diode in rectifying AC signals.

How does a propeller vehicle use air resistance?
A propeller vehicle uses air resistance to generate forward thrust. As the propeller spins, it creates a pressure difference between the front and back of the propeller, causing the vehicle to move forward. The air resistance acts against the motion of the propeller, helping to propel the vehicle forward.
What goes backward gets lighter and forward gets heavier?
A feather. As you move a feather backwards, it feels lighter due to air resistance, whereas moving it forward increases the resistance, making it feel heavier.
What are two forces that resist the forward motion of a bus?
Two forces that resist the forward motion of a bus are air resistance (drag) acting in the opposite direction of movement and friction between the tires and the road surface.
What is a Forward motion and resistance to slowing?
Forward motion refers to movement in a particular direction, while resistance to slowing refers to the force opposing a decrease in speed. Both concepts are fundamental to understanding the dynamics of motion and how objects interact with their environment.
Which force on an airplane can also be called a resistance force?
Drag force on an airplane is often referred to as a resistance force. It is the force that opposes the forward motion of the airplane and is caused by air resistance.
What is the behavior of a forward and reverse biased diode?
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
What is the importance of the reverse-to-forward resistance ratio of a diode?
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 .
How do you find the ac resistance of a diode?
The ac resistance of a diode is found using the equation: (The change in Vd)/(The change in Id) An easier was is to use the Equation: 26mV / Id. This is a general form as the ac resistance of a diode change as the temperature changes.
Do swim costumes reduce resistance and drag in the water?
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;
Why resistance doesnot depend on frequency of ac?
Because Resistance is material property...
What is the opposition to the current flow?
resistance is the opposition to the flow of electric charge
What is ac resistance of a diode?
ratio of ac voltage applied across the diode to the ac current flowing through it
What is the total opposition to a current flow in an AC circuit with both resistance and reactance?
Resistance
What is a difference between DC and ac resistance and expline DC resistasce?
DC is just direct current into a resistance it is a linear function. AC if the resistance is non reactive it would be the same linear function.
Compare the sizes of forward force and air resistance while a car is moving at 30mph?
when a car is speeding up how does the forward force and air resistance compare
Who is the top forward in AC Milan?
Zlatan Ibrahimovic
How physics affects flying?
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
