Homework 1 Due: Wednesday, August 24 1 (a) Suppose the charge transported across the cross section of the conductor for t 0 is q ( t ) = e - 2 cos (48 π t ) C. Find the current, i ( t ), t 0, ﬂowing in the conductor. (b) The charge crossing a boundary in a wire is given in Figure 1 for t 0. Plot the current i ( t ) through the wire. (Note that a similar problem was considered in the course textbook – see Example 1.2) 2 4 6 8 10 t L secs R M 1 1 2 3 q L t R L C R Figure 1: Charge crossing a hypothetical boundary.

Unformatted text preview: 1 2 (a) The current in an ideal conductor is given by i ( t ) = 2-e-3 t-cos(4 t ) A for t ≥ and 0 for t < 0. Determine the charge transferred, q ( t ) as a function of time for t ≥ 0. (b) Repeat part (a) for the current plot sketched in Figure 2. Again, the current is zero for t < 0. 1 2 3 4 t L secs R M 2 M 1 1 2 i L t R L A R Figure 2: Current in a conductor as a function of time 2...
