- State and explain ohm’s law and Kirchoff’s law and solve simple problems
- Derive equivalent resistance of series and parallel circuits
- Solve problems in mesh current and nodal voltage method
- State and explain super position theorem, Thevinin’s theorem, Norton’s theorem and maximum power transfer theorem and solve problems in theorems
- Explain 3^ power measurement by two watt meter method
- Explain constructional details of dc machines
- Explain the construction, working and starting methods of 1^ &3^ induction motor
- Explain the principle and working of different types of induction motor
- Explain the principle and working of transformer
