Q) Diamond is a paramagnetic material?
A) Diamond is diamagnetic.
Q) Which capacitor-store higher amount of energy?
A) Energy stored is proportional to capacitance and capacitance is proportional to permittivity.
Q) Above ferroelectric curie temperature, spontaneous polarization in ferroelectric materials becomes stronger?
A) Spontaneous polarization vanishes above ferro-electric Curie temperature.
Q) In paramagnetic materials?
A) In paramagnetic materials interaction between neighbouring dipoles is negligible.
Q) The conductivity of intrinsic semiconductor is given by?
A) For intrinsic semiconductor,
Conductivity = (Electron charge) x (Number of charge carriers) x (Sum of mobilities of holes and electrons).
