WebDynamic resistance is the resistance offered by a diode to changing forward current. Due to the application of AC voltage, the AC current will flow in the circuit. Hence, the instantaneous value of the operating point changes because of the input value in AC current changes with time. WebThe ac resistance of the core, sheath or armour can be calculated from the dc resistance using the following formula: (3.104a) R ( ac ) = R ( dc ) [ 1 + y ( k S + k P ) ] Ω / km …

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.
