2 2 Simple Physics for Complex Biology Ohm’s Law:  V (volt)  R (ohm)  I (coulomb/s) Capacitor:  C (farad)

3 3 Exercise Use MATLAB to plot the voltage- current relationship for different conductance. Try to plot: Given a time course of Q such as plot the time course of the current I resulted from Q(t).

4 4 Simple Physics for Complex Biology R-C Circuit (charging) Cell Membrane

5 5 Exercise We have learned how to solve the charging-type RC circuit, please try to solve the discharging-type RC circuit as shown below: (plot your result Q(t) in MATLAB)

6 6 Simple Physics for Complex Biology Boltzmann Statistics Reversal Potential (exercise)
