The L-shaped conductor as shown in figure moves a 10 m//s across a stationary L-shaped conductor in a 0.10 T magnetic field. The two vertices overlap so that the enclosed area is zero at t-0 The conductor has resistance of 0.010 ohms per meter. What is current (in Amp) att=0 10 sec (Round off to nearest integer) |
Answer»  `x=10t` `phi=B[(10t)/sqrt(2)]^(2)` `(dphi)/(DT)=100Bt=100xx(.10)XX(.10)=1V(dphi)/(dt)=100Bt=100xx(.10)xx(.10)=1V` `R=(.10)xx4((10t)/sqrt(2))` `i=I/R (dphi)/(dt)=35.35 approx 35 A` |
