Question No. 140

The voltage across the capacitor, as shown in the figure, is expressed as

${V}_{c}\left(t\right)={A}_{1}\mathrm{sin}\left({\omega }_{1}t-{\theta }_{1}\right)+{A}_{2}\mathrm{sin}\left({\omega }_{2}t-{\theta }_{2}\right)$

The values of  A 1and  A 2 respectively, are

Question No. 7

A source ${\nu }_{s}\left(t\right)=V\mathrm{cos}100\pi t$ has an internal impedance of $\left(4+j3\right)\mathrm{\Omega }$.If a purely resistive load connected to this source has to extract the maximum power out of the source, its value in $\mathrm{\Omega }$ should be

In the circuit shown below, if the source voltage ${V}_{s}=100\angle 53.13°\mathrm{V}$ then Thevenin’s equivalent voltage in Volts as seen by the load resistance RL is
