Consider the RC circuit in Figure 2 below. Assuming the switch has been open for a long time before it is closed, fill in a table providing the current through each component and the voltage across each component immediately after the switch is closed, and a very long time after the switch is closed. Next, figure out the time constant for the circuit. (Hint: Assign currents to each branch. Set up the necessary KVL and KCL equations. Eliminate all but one variable to get an equation for just one of the currents. You shouldn’t have to solve this equation to recognize the time constant!)
