Apply Ohm's law and the power equation to solve at least 20 numerical problems covering single resistors, series strings and parallel branches.

Distinguish AC from DC supply and list the standard Indian domestic and industrial voltage levels with their typical applications.

Identify the standard symbols used in circuit diagrams and reproduce them accurately in a hand-drawn symbol sheet.

Explain the construction and working principle of a single-phase transformer and state why it cannot change frequency.

Compare the construction, starting torque and applications of induction, synchronous and DC motors in a written summary.

Describe the parts and function of a distribution transformer, including bushings, conservator, breather and earthing terminal.
