A wafer of titanium dioxide (κ = 173) has an area of 1.25 cm^2 and a thickness of 0.140 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?
free charge C/m^2
induced charge C/m^2
(d) What is the magnitude E of the electric field?
V/m
