A) 0.27 A
B) 0.37 A
C) 1.0 A
D) 0.72A
Correct Answer: A
Solution :
[a] The induced emf across the sliding wire \[e=Bv\ell =0.5\times 4\times 0.25=0.5\,V\] The effective circuit is shown in figure. The equivalent resistance of the circuit \[r=\frac{4\times 2}{4+2}+0.5=1.83\Omega \] Now, \[i=\frac{V}{R}=\frac{0.5}{1.83}=0.27\,A\]You need to login to perform this action.
