The two ends of a rod of length `L` and a uniform cross-sectional area `A` are kept at two temperature `T_(1)` and `T_(2)` `(T_(1) gt T_(2))`. The rate of heat transfer. `(dQ)/(dt)`, through the rod in a steady state is given by

A

`(dQ)/(dt) = (KL (T_(1) - T_(2)))/(A)`

B

`(dQ)/(dt) = (L(T_(1) - T_(2)))/(LA)`

C

`(dQ)/(dt) = KLA (T_(1) - T_(2))`

D
