The current (I) in the inductance is varying with time according to the plot shown in figure. Which one of the following is the correct variation of voltage with time in the coil?

Multiple Choice Options

  • A Q4πR2σ{Q \over {4\pi {R^2}\sigma }} 4 � R 2 _ Q _
  • B (Q4πR2σ)−1/2{\left( {{Q \over {4\pi {R^2}\sigma }}} \right)^{ - 1/2}} ( 4 � R 2 _ Q _ ) _ 1/2
  • C (4πR2Qσ)1/4{\left( {{{4\pi {R^2}Q} \over \sigma }} \right)^{1/4}} ( _ 4 � R 2 Q _ ) 1/4
  • D (Q4πR2σ)1/4{\left( {{Q \over {4\pi {R^2}\sigma }}} \right)^{1/4}} ( 4 � R 2 _ Q _ ) 1/4
