A wafer of titanium dioxide (1 = 173) of area 1.00 cm2 has a thickness of 0.100 mm. Aluminum is evaporated on the parallel faces to form a parallel-plate capacitor.
(a) Calculate the capacitance.
(b) When the capacitor is charged with a 12.0-V battery, what is the magnitude of charge delivered to each plate?
(c) For the situation in part (b), what are the free and induced surface charge densities?
(d) What is the magnitude of the electric field?
