WebAir resistance is a force that is originated by air. This force works in a conflicting direction to a body passing through the air. Air resistance applies the frictional force of air against a moving body. As a body moves, air resistance slows it down. The quicker the body’s movement, the superior the air resistance applied again’st it. WebHowever, unlike the junction diode which is a two layer ( P-N ) semiconductor device, or the commonly used bipolar transistor which is a three layer ( P-N-P, or N-P-N ) switching device, the Thyristor is a four layer ( P-N-P-N ) semiconductor device that contains three PN junctions in series, and is represented by the symbol as shown..
