Question: Explain why the electric field between two parallel plates of
Explain why the electric field between two parallel plates of a capacitor decreases when a dielectric is inserted if the capacitor is not connected to a power sup-ply, but remains the same when it is connected to a power supply.
Answer to relevant QuestionsUnder what conditions would two capacitors in series have the same voltage across them? What if they were in parallel? How much work is required to completely separate two charges (each -1.4μC) and leave them at rest if they were initially 8.0 mm apart? What is the value of electric potential at (a) The center of the square and (b) A point midway between q1 and q4 in Fig. 16.25? (a) The equipotential surfaces in the neighborhood of a positive point charge are spheres. Which sphere is associated with the higher electric potential: (1) the smaller one, (2) the larger one, or (3) they are associated ...Repeat Exercise 33 if the plates are instead connected to a 24-V battery. Also determine the electric field (direction and magnitude) at the midway point between the plates. Compare your answers to Exercise 33 and comment on ...
