a) Explain the physical meaning of Ē = – V. If electric potential, V = 2xy + 9xyz + 20yz then calculate V and Ē at point (3, 5, 9) b) Electric field can be created either by a voltage source or by time varying magnetic field. Between these two cases, for which o E. dl Write down the differences between conducting current density (Jc) and displacement current density (Ja) = 0 will be true? Explain.
