In the circuit of figure, the battery emf is g the resitance is R and the capacitance is C. The switch S is closed for a long time interval, and zero potential difference is measured across the capacitor After the switch is opened. the potential difference across the capacitor reaches a maximum value of DeltaV. What is the value of the inductance?

Answer»

`(C(DeltaV)^(2))/(2epsi^(2))`
`(C(DeltaV)^(2))/(epsi^(2))`
`(2C(DeltaV)^(2))/(epsi^(2))`
`(C(DeltaV)^(2))/(4epsi^(2))`
