Discharging a Capacitor Through a Resistor

%% Discharging a Capacitor Through a Resistor
% Calculates the voltage across a capacitors after a certain amount of time
%   passes. Notes and clarifications are at the end of the code

% Inputs and Variables
C = input('What is the capacitance in Faradays?\n');
V0 = input('What is the initial potential difference across the circuit in volts?\n');
R = input('What is the resistance in ohms?\n');
t = input('How many seconds later?\n');

% Outputs and Equations
V = V0*exp(-t/(R*C))
fprintf('The new potential difference is %.4e V', V);

%{
The output is rounded to after the 4th decimal place. You can change this by
    adjusting or removing the .# in the fprintf line.
