Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

there is not any necessary theory this is only sign convention. if we assign a loop and we are going from negative to positive it means rise in potential then we take positive sign and if we assign the loop direction in positive to negative it means we are coming from higher potential to lower potential then we use negative sign, otherwise not any such theory.
madam maxwell mesh current theory madam
madam please share your opinion
ma'am 1st eqn should have been i1r1+(i1-i2)r2-E1=0
but it is given almost opposite
i will clear. wait
see the attachment.
now let me know, if still any doubts
resistance is taken as fall in potential because it is passive element?
ma'am what about inductor and capacitor?
inductor and capacitor are also passive components
