1-How could an RL combination be connected to produce an output voltage which is the time derivative of the input voltage?(adsbygoogle = window.adsbygoogle || []).push({});

2-Show that taking the time derivative of a sinusoidal function [such as cos(wt+a)] always has the effecton increasing its phase pi/2.

3-İf the internal series resistance of an inductor is not negligible , how will this change the relative phase of voltage and current fort he inductor?
