Shown below are four RC circuits labelled A, B, C, and D. Each has some combination of batteries with emf & = 4.5 V, resistors with resistance R = 15 k2, and a capacitor with capacitance C = 2.5 /F. For each factor of 1/e. circuit, find the amount of time (in seconds, to two significant digits) it takes for the current to decay by a R A R R m E C C C R R D m E R C
