Physics Question on Units and measurement

The unit of thermal conductance is

A

WK−1 WK^{ - 1}

B

JK−1 JK^{ - 1}

C

WK

D

JK

Answer

WK−1 WK^{ - 1}

Explanation

Solution

Thermal conductance = △Qt△ θ\frac{ \triangle Q }{ t \triangle \, \theta } = JsK\frac{ J }{ sK } = JsK−1\frac{ J }{ s} K^{ - 1} = WK−1WK^{ - 1}
