In Fig.19-56 (same as Fig. 19-20a), the total resistance is 15.0k, and the batterys emf is 24.V.

In Fig.19-56 (same as Fig. 19-20a), the total resistance is 15.0kΩ, and the battery€™s emf is 24.V. If the time constant is measured to be 35.0μs, calculate (a) The total capacitance of the circuit and (b) The time it takes for the voltage across the resistor to reach 16.0V after the switch is closed.
