Solve the all parts of given problem:
Problem: A series combination has a battery (V = 18V), a switch (initially open), a resistor (R = 450 ohm), and a capacitor (C = 22.0 µF). When the switch is closed a clock is started (t = 0.0 sec). Determine the time constant for the circuit. Sketch a voltage on the capacitor, VC, versus time.
Part A: Calculate the capacitor voltage after two time constants have elapsed. Sketch the voltage on the resistor, VR, versus time.
Part B: Calculate the resistor voltage after two time constants have elapsed.
Please explain how you got the numbers and calculations. Thanks.
