The three circuit elements shown in the figure are part of an electric circuit. The total power absorbed by the three circuit elements in watts is ________________.

C₀ is the capacitance of a parallel plate capacitor with air as dielectric (as in figure (a)). If, half of the entire gap as shown in figure (b) is filled with a dielectric of permittivity $$\in_r$$ , the expression for the modified capacitance is

Consider a delta connection of resistors and it's equivalent star connection as shown below. If all elements of the delta connection are scaled by a factor k, k>0, the elements of the corresponding star equivalent will be scaled by a factor of
