(5) A leaky and initially charged (Qo) parallel plate capacitor is slowly discharging via current leakage through the material between the plates (but with dielectric constant K = 1). The area

of the plates is A and the separation is d. The total current between the two plates is assumed to be lo, independent of time. Assume/ is small enough that the magnetic field produced is also small. Evaluate all the terms in the Poynting theorem and explain what is happening.
