Superposition Theorem

In trying to solve dpps in current electricity

  1. The use of superposition theorem greatly helps.
  2. one important thing in applying it is to keep the internal resistance when shorting the battery.
  3. Other useful concept is Node method in analysing the circuits.
  4. These two concepts greatly simplify  as an alternative to elaborate Kirchoff’s laws.

IRODOV’s Solutions

Problems in Physics by I E Irodov is a celebrated book in Physics.

  1. It contains problems with multiple concepts.
  2. Different versions of solutions are available but I would prefer  Abhay Kumar Singh’s solutions by Wiley
  3. Good collection of electrical circuit problems and discussion by Jaan Kalda here

Current Electricity

We are starting current electricity from today in my daughters prep.

  1. Current Electricity questions seem to be relatively straight forward compared to Mechanics.
  2. This week focus is on Kirchhoff’s Laws- Wheat Stone bridge, Conversion of MCG to Ammeter and Voltmeter, Meter Bridge,Potentiometer.
  3. We are focusing on problems from Irodov,AK Singh as they will give solid foundation for the thinking process.
  4. We would start with HC Verma, question banks from Deepti and Telugu academy will be done.

Electrodynamics for IITJEE

Hita is starting  Sr.CO-IPL from today in her quest for IIT-JEE.

  1. I would like to support her in physics prep.
  2. I am a physics enthusiast and that helps. With Dora’s top class guidance hope she can do wonders.
  3. We would be intensely preparing Electrodynamics with IRODOV and A K Singh
  4. If the copy right and authors permit, I would be posting some discussion on AK Singh’s questions as Dora would discuss with Hita.
  5. Irodov’s solutions are already available from Wiley authored by AK Singh.
