The ac resistance of the emitter diode equals the ac base-emitter voltage divided by the ac emitter current.

Question

This statement is true according to the equation for the ac resistance of a diode, which is r = Δv/Δi. In this case, the ac base-emitter voltage is the change in voltage across the base-emitter junction, and the ac emitter current is the change in current flowing through the emitter terminal. Therefore, r = Δv/Δi = ΔVbe/ΔIe, where Vbe is the base-emitter voltage and Ie is the emitter current.
