Q1- During the time interval between t = 0 and t = 17 s, the total charge that crossed a plane across a wire at time t is given by (16C)(1-e-t/5.8s)where t is in seconds. What is the maximum value of the current? What is the current at t = 5.8 s?
Q2- A tube of mercury with a resistivity of 9.84 x 10-7 Ohm.m, has a 17.0 N/C electric field inside the column of mercury. How much current is flowing, if the diameter of the tube is 2.0 mm?
