Lecture 1 figures 2 Fig. 1-5: Charged body. Fig. 1-6: Determining i(t)from q(t).Fig. 1-8: Determining q(t)fromi(t). Ex: The net charge q(t)on a body changes as shown in the plot. Plot a qualitative sketch of the current i(t). Fig. 1-7: Determining i(t)from q(t).Ex: The current in a wire is given by i(t)= 1 mA cos(2p100 t). Determine the net charge that has
