Chapter 10: Problem 11
A dc voltage equal to \(V_{\mathrm{dc}} \mathrm{V}\) is applied to a resistor of \(R \Omega .\) A sinusoidal voltage equal to \(v_{s} V\) is also applied to a resistor of \(R \Omega\). Show that the de voltage will deliver the same amount of energy in \(T\) seconds (where \(T\) is the period of the sinusoidal voltage \()\) as the sinusoidal voltage provided \(V_{\mathrm{dc}}\) equals the rms value of \(v_{s}\). (Hint: Equate the two expressions for the energy delivered to the resistor.)
