(a) What is the expression for the voltage across a capacitor as itis discharging in a series circuit. Use V_0 (upper case Vunderscore zero) for the initial voltage, R for the resistor, C forthe capacitance, and t for the time. Use exp(x) to denote theexponential function.V =(b) What is the significance of the voltage across a capacitor asit is DIScharging in a series circuit when t = t? (from aboveequation)(c) What is the significance of the voltage across a capacitor asit is charging in a series circuit when t = t?
A fully charged capacitor with a voltage of 120 kV is dischargedthrough a resistor.
