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 _{1}and A _{2} respectively, are
The total power dissipated in the circuit, shown in the figure, is 1 kW.
The voltmeter, across the load, reads 200 V. The value of X_{L} is ___________.
A source ${\nu}_{s}\left(t\right)=V\mathrm{cos}100\pi t$ has an internal impedance of $(4+j3)\mathrm{\Omega}$.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 ${V}_{s}=100\angle 53.13\xb0\mathrm{V}$ then Thevenin’s equivalent voltage in Volts as seen by the load resistance R_{L} is
Two magnetically uncoupled inductive coils have Q factors q_{1} and q_{2} at the chosen operating frequency. Their respective resistances are R_{1} and R_{2}. When connected in series, their effective Q factor at the same operating frequency is
