Fill in 3 Table 3. Two voltage sources in series: KVL and calculating resistance. Voltage Vs Add.

(Later) Plot Vs (y-axis) vs. I (x-axis) in MATLAB using this syntax: x=[]; This command defines a row vector x. Place real numbers within the square brackets separated by spaces or commas. Do the same for y values. Semicolon at the end suppresses display of variable try the command with and without it. – plot(x,y,’o’) This command plots the data in vectors x and y and does not connect lines between each point. Save the graph in png format using this command (for jpeg use instead of “jpeg” “png”): print myplot (where is filename) “myplot” –dpng By default MATLAB stores these files in your local directory (check where this is typically located). Insert your MATLAB plot here (use drag-and-drop or the menu in Word). “insert” From this plot estimate the value of R, slope of the curve and y-intercept point: slope = _______________ y-intercept= _____________ To what component of circuit does the y-intercept of this plot correspond?
