Hy, am also 12th student from Chennai.. Fr ohm meter, I dnt kno, may b urs crct.. Bt bandwidth question u came near bt d ans s either.. My explanation ; as u tld its bright dark bright dark.. Bandwidth explanation s distance between consecutive bright or dark, den between two, only 1 wl present..!!
If u calculate distance, will u consider the starting or ending point of both fringes, like I did. Or the ending point of one and the starting of another.
Actually, the parts of the rectifier are actually diodes, the resistor and their interconnections. The coils are from the transformer. The transformer is not part of the rectifier circuit. A coil is not a source of self-induced emf. The definition of self-induction is "property of a coil which enables to produce an opposing induced emf in it when the current in the coil changes." An emf is induced in the coil only when a source of emf (battery) is connected as shown in fig 4.5 in our Physics Volume-I textbook
@ abdul ; I too wrote d same, after only I came go kno dat, according to our book work done s directly proportional to rotation.. So 90 degree means -PE COS 90 s 0.. Bt I believe board wl gve marks fr both PE nd 0..:)
no palaniappan.....now wen the dipole is parallel to field it has max potential tat is zero and as u say wen it is aligned with field it has minimum potential tat is -pe ....and they are asking u the work done....for tat u hv to make -pe as zero...and we can do tat only by adding pe....so pe is the work done
If its PE, am pretty happy.. Because I too wrote d same with d same logic u told, my mam told its directly proportional to rotation, so explained as my mam..!!

DeleteHy dharsaun, I dnt kno abt 16, it's nt confirm til nw, bt 11th one confirm along AB, bt 22 its either dark r bright.. !!
Delete16.c. Ohmmeter.
Deletesuppose two answers are correct in any question,would they give for only those two,or for mere attempt? plese clarify
Deletewould they give mark for only those two or for mere attempt?

Bt bandwidth question u came near bt d ans s either..
My explanation ; as u tld its bright dark bright dark.. Bandwidth explanation s distance between consecutive bright or dark, den between two, only 1 wl present..!!
yeah either bright or dark band but the question was not clear
DeleteIf u calculate distance, will u consider the starting or ending point of both fringes, like I did. Or the ending point of one and the starting of another.
DeleteIf we calculate from end point to start point only, we wl gt distance, den either only na..??
Deletehello aurobindo...i guess for 16th question...which has self induced emf..in tat case rectifier has coli and it must have a self induced emf....rit?

DeleteYes. It'll act along AB. It'll not be zero.
