[@ksingh7149]

Great work indeed 👏 👍 👌 .

[@maxivides]

It was a very good explanation but there is one thing I did not understand, how did you get M*(di1di2) from M*(i1di2+ i2di1)?

[@-AdarshVulli]

D(uv)=udv+vdu method

Sir can we get notes of today's class?

[@shivanshutripathi460]

Co efficient of coupling cannot be negative naa sir ?
