Three identical metal plates of area 'A'...

Three identical metal plates of area 'A' are at distance `d_1 & d_2` from each other. Metal plate A is uncharged, while plate B & C have respectively charge+q & - q . If metal plates A &C are connected by switch K through a consumer of unknown resistance. What energy dose the. Consumer give out to its surrounding ?
Assume `d_1 = d_2= d`

A

`(q^2d)/(4epsilon_0A)`

B

`(q^2d)/(epsilon_0A)`

C
