Answer 1

Your PR matrix now holds values of power (in watts) delivered to the resistor for every combination
of inductor (L) and capacitor (C) values. Declare a new scalar variable max PR to store
the largest value of power inside the PR matrix.
Use your results to report which specific value for L and value for C resulted in max PR. Store
these two results in the variables max L and max C, respectively. The find function should be
instrumental here. More specifically, see its usage near the top of p. 178 in your textbook.

Answer 2

I was told by phi I need to use double indexing for this part.

Answer 3

The double indexing is confusing me.

Answer 4

hmm still thinking

Answer 5

sorry I'm getting lost in all the circuit analysis. I'm not exactly sure what they're even asking for

Answer 6

let me explain to you

Answer 7

hold on for a sec

Answer 8

% defining input variables for RLC circuit

f_volt = 60; % measured in hertz
W_volt = 120; % measured in volts rms
R = 100; % measured in ohms

L_o = 0.005:0.005:0.245; % matrix L 2D matrix incr. from left to right
C_o = 5e-6:10e-10:9.5e-5; % matrix C 2D matrix incr. from top to bottom

[L_o, C_o] = meshgrid(L_o, C_o);

% current output for RLC circuit (I) in RLC circuit (note: j = sqrt(-1))
I = (120)./(100 + j*2*pi*60*L_o - ((j)./(2*pi*60*C_o)));

% power obsorbed by resistor
P_R = 100*abs(I.^2);

Answer 9

so here we have my variables (inputs) and my two vectors L is the inductor and C is the capacitor. We then perform a meshgrid. The current equation I gives me the current in the RLC circt. P_R is the power that the resistor absorbs.
