2. Draw, in the spaces provided, rough sketches shov ing the following: a) A current which lags the voltage by 60°. b) A current which lead the voltage by 60°. c) A current which lags the voltage by 180°.

Q.5. List the factors that determine the lifting capability of an electromagnet. Given the fact that a U shaped electromagnet will double the lifting force of a straight electromagnet (all other factors being equal). Show how you may double the lifting force of a U shaped electromagnet without changing any of its electrical parameters.
