Problem: A series combination has a battery (V = 18V), a switch (initially open), a resistor (R = 450 ), and a capacitor (C = 22.0 F). When the switch is closed a clock is started (t = 0.0 sec).
Part A: Determine the time constant for the circuit. Sketch a voltage on the capacitor, VC, versus time.
Part B: Calculate the capacitor voltage after two time constants have elapsed. Sketch the voltage on the resistor, VR, versus time.
Part C: Calculate the resistor voltage after two time constants have elapsed.
I want help to calculate the capacitor voltage after two time constants have elapsed.
