For one mole of an ideal gas which of the following relation is correct?
View answer and explanation
Correct option: C
(∂P∂T)V(∂T∂V)P(∂V∂P)T=−1\left(\frac{\partial \mathrm{P}}{\partial \mathrm{T}}\right)_{\mathrm{V}}\left(\frac{\partial \mathrm{T}}{\partial \mathrm{V}}\right)_{\mathrm{P}}\left(\frac{\partial \mathrm{V}}{\partial \mathrm{P}}\right)_{\mathrm{T}}=-1
The correct answer is B because maximum current is obtained when the external resistance is much smaller than the equivalent internal resistance of the parallel combination of cells.
