Sir kindly make me clear in question(no.21 and 24) and also in (31 and 35)these question are confusing...
good
21-b ,24- b 31-d
Thanks .....Yogendra but i think 21-a 24-a and 31-d as per max trnsf theoram.
thanks sir
34 b
thanks :)
millman s theorem is not applicable for current source , its convert first than apply,
35 option is may be wrong
maximum power transfer theorem is given by thevnins theorem , and \\
