I am uploading the last part of A C Circuits. Two articless: Series LCR circuits & Transformer have been discussed in this part.
Both are important from examination point of view. Do not forget to practice diagrams. Follow up by trying Previous year questions. You may write to me in case you need practice questions on this unit. HAPPY LEARNING!
Another simple but very important topic A C Generator/Dynamo is here. It is generally asked as 3 to 5 marks question.
Do practice the diagram.
Remember: The diagram should be neat and labelled.
Power in A C Circuits part 2 contains derivation of expression for power consumed in A C circuits. It also explains the terms wattless current and power factor.
As desired by the students, I am posting A C Ciruits.
Part 1 is here for you.
Part 2 and 3 will follow soon.
PS: After having studied the unit CURRENT ELECTRICITY, do follow up with written practice of derivations and CBSE previous year problems.
You may request for a comprehensive exercise on the same. It will be mailed to you.
