162390 Which of the following about polar molecule is true?
I. A polar molecule is one in which the centres of positive and negative charges are separated.
II. Polar molecule has no permanent dipole moment.
III. An ionic molecule such as \(\mathrm{HCl}\) are examples of polar molecules.

162391 If the electron drift speed is so small, and the electron's charge is small, how can we still obtain large amounts of current in a conductor?

162392 The resistance of the platinum wire of a platinum resistance thermometer at the ice point is \(5 \Omega\) and at steam point is \(5.23 \Omega\). When the thermometer is inserted in a hot bath, the resistance of the platinum wire is \(5.795 \Omega\). Calculate the temperature of the bath.

162393 The four arms of a Wheatstone bridge have the following resistances: \(A B=100 \Omega, B C=10 \Omega\), \(C D=5 \Omega\), and \(D A=60 \Omega\). A galvanometer of \(15 \Omega\). resistance is connected across \(B D\). Calculate the current through the galvanometer when a potential difference of \(10 \mathrm{~V}\) is maintained across AC.
