While discharging, what happens to the voltage in the capacitive circuit?(a) Decreases linearly(b) Increases linearly(c) Decreases exponentially(d) Increases exponentiallyThe question was asked in an international level competition.My doubt stems from Growth and Decay topic in section Capacitance and Capacitors of Basic Electrical Engineering

Answer» RIGHT choice is (c) DECREASES exponentially

The best EXPLANATION: The equation for the value of VOLTAGE in a DISCHARGING capacitive circuit is:

V=V0(e^-t/RC). From this equation, we can see that the voltage is exponentially decreasing.
