Unformatted text preview: ˚ C.” We further found out the current flowing through the cell membrane to be 53mA in the above setup. Now assume that in addition to resistance, the membrane also has some capacity to store charge, given by its capacitance. If the capacitance of the membrane is 7pF, find out the number of ions (not the charge) that is stored in the membrane at any given time instant. 4. MATLAB (10 points) Write a matlab script to plot the input voltage and output voltage of the Op Amp shown below. Suppose that R 1 = 2 k Ohms , R 2 = 50 k Ohms , R 3 = 30 k Ohms and v s = 4 cos (2000 t) V. And the saturation voltage is V sat =15 V, which means the absolute value of output voltage cannot exceed V sat (HINT: The output voltage become flat if it reaches saturation voltage) Vs...
