What is AC forward resistance?
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.
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 .
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;
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
Draw a free-body diagram of a football being kicked?
A free-body diagram of a football being kicked would include forces such as gravity pulling the ball downward, the force exerted by the kicker's foot pushing the ball forward, and air resistance opposing the ball's motion. The diagram would show these forces acting on the football as vectors.
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
The bluk resistance of a diode depends on?
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.
Does friction opposes walking?
Friction provides the force needed for walking by creating a grip between your shoes and the ground. This grip allows you to push off the ground and move forward. Without friction, it would be difficult to walk as there would be no resistance to help you move forward.
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
How do you identify the polarity of a diode when the tester is on resistance scale?
ln reverse biase high resistance and in forward biase very low resistance
What keeps a car from going forward?
Air resistance and friction.
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.
