Solution
9) A) B*L*v/R counter clockwise
Induced emf = B*L*v
induced current = induced emf/R
= B*L*v/R
the direction of induced current is always such as to oppose the change in magnetic flux that generated it.
so, induced current direction must be clouner clockwise.
10) B) Bc = mue*epsilon*pi*r^2*E1/T
because, displacement current, Id = A*epsilon*dE/dt
= pi*r^2*epsilon*E1/T
using Ampere-Maxwell\'s equation
integral Bc*dL = mue*Id
Bc*2*pi*r = mue*pi*r^2*epsilon*E1/T
Bc = mue*epsilon*r*E1/(2*T)
Bc = mue*epsilon*A*dE/dt
= mue*epsilon*pi*r^2*E1/T
11) D) may increase or decrease depending on the value of the resonant frequency.
at resonant frequency the rms current through the circuit is maximum.
if the frequency of the source is less than or greater than resonant frequency the rms current decreases.
