AC Circuit with R and C

%% AC Circuit with R and C
% Determines the RMS current, RMS voltage across the resistor and
% capacitor, and the phase angle for the circuit

% Inputs and Variables
C = input('What is the capacitance?\n');
R = input('What is the resistance?\n');
Vrms = input('What is the voltage RMS output?\n');
f = input('What is the frequency? \n');

% Outputs and Equations
Xc = 1/(2*pi*f*C);
Irms = Vrms/sqrt(R^2+Xc^2);
phi = atan(-Xc/R);
VrRMS = Vrms*cos(phi);
VcRMS = -Vrms*sin(phi);
fprintf(['The RMS values for the current, voltage across resistor and capacitor, and phase angle are:\n',...
         '%.3e A, %.3e V, %.3e V, %.3e rad'],Irms, VrRMS, VcRMS, phi)
%{
The trig functions and phase angle are calculated using radians. To change
this adjust the trig functions to read atand, cosd, and sind. Also change
the second fprintf line to read degrees
