The current generator `I _g`, shown in . Sends a constant current I throught the curcuti. The wire cd is fixed and ab is made ot slide on the smooth, thick rails with a constant velocity v towards right. Each of these wire has resistance r. Find the current through the wire cd.

Text Solution

Verified by Experts

Initial Current passed =i
Hence initial emf=ir
emf due to motion of ab=Blv
Net emf =ir-Blv
Net resistance =2r
Hence Current passed =(ir-Blv)/(2r).`
