Dynamic Emitter Resistance Formula

LaTeX Go

Dynamic Emitter Resistance = 0.026/Emitter Current
R_e = 0.026/I_e

Is AC resistance the same as DC resistance?

The AC resistance is more than the DC resistance because the alternating current flowing through the conductor does not distribute uniformly and concentrates near the surface of the conductor and thus the effective cross-section area decrease and the resistance increase.
