Power dissipated in an L-C-R series circuit connected to an AC source of emf epsilon is

Answer»

`(EPSILON^(2)R)/([R^(2)+(Lomega-(1)/(Comega))^(2)])`
`(epsilon^(2)[R^(2)+(Lomega-(1)/(Comega))^(2)])/(R)`
`(epsilon^(2)[R^(2)+(Lomega+(1)/(Comega))^(2)])/(R)`
`(epsilon^(2)R)/(SQRT(R^(2)+(Lomega-(1)/(Comega))^(2)))`
