A coil having n turns and resistance R W is connected with a galvanometer of resistance \[4R\Omega \]. This combination is moved in time t seconds from a magnetic field W1 weber to W2 weber. The induced current in the circuit is [AIEEE 2004]

\[-\frac{({{W}_{2}}-{{W}_{1}})}{Rnt}\]

\[-\frac{{{W}_{2}}-{{W}_{1}}}{5\ Rnt}\]

\[-\frac{n({{W}_{2}}-{{W}_{1}})}{5\ Rt}\]

\[-\frac{n({{W}_{2}}-{{W}_{1}})}{Rt}\]
