1. Examine the polarization of a heart shown below. Then, for each of the three ECG setups, predict the Voltage vs Time graph that you would expect to see on the ECG reading. (a) (b) (c) Atrial depolarization Septal depolarization Ventricular depolarization AV AV a b c a b c 2. Based on your graph, which placement would be the best one to use to measure the heart beat? Explain your reasoning. 3. Two different charged plate setups are shown below. One has a capacitor between the plates and the other has an insulator (dielectric) between the plates. a. Draw the electric field lines created by the plates both outside and inside the objects (conductor or insulator). Be sure to visually represent any changes in electric field magnitude. b. Show the configuration of charges in the conductor and insulator that result from the electric field. C. Draw equipotential lines based on your field lines and your understanding of conductors and insulators. d. Draw an electric dipole moment vector (or indicate that it is zero) for e. each object (conductor and insulator) Explain the differences in your models and how each object affects the electric field and electric potential in the overall setup. + Vacuum Conductor + + Insulator + 1.
