2) Write a (very simple) system of one equation to solve for the voltage values in the circuit. (Y will be doing a similar problem, but with 3 unknowns in your ou homework problems. In electrical circuits the current, voltage, and resistor values are related by the Kirchoff Voltage Law, which says the sum of voltages around a loop must be zero. The voltage along a resistor is also related to the currents by a linear equation. Therefore, ifyou know the voltages and resistor values, you can solve for the currents using a linear system of equations which can be computed using MATLAB's matrix left division (ie, these equations are of the form Ax b). So in the picture below there are two voltages (V, and the voltage at R, which is -R*i). The sum of the two must be zero

Explanation / Answer

The MATLAB code is given as:

%The equation is given as: V - i*R = 0
%The rearranged equation is R*i=V
%Here we have to solve for i
R=3;
V=10;
i=RV;
disp(i)

We obtain i = 3.333

Now putting the value of i in the original equation we see that the total voltage around the loop is indeed 0.
