\partialV/\partialt=Re(jwVsexp(jwt)).
This means taking the real part ,of phasor form multiplied with exp(jwt), gives you back the time domain form of V.
Here phasor form is jwVs.
Normally this type of problem is encountered in transmission line theory.Here the derivative must be replaced by partial derivative.V is being converted to frequency domain in this problem.This is called the phasor form.This type of conversion reduces the computation steps involved in the time...
This is a clamper circuit.When the input is at its negative peak,the diode is on and the capacitor is charged opposite to what is shown in the circuit.The capacitor is charged to V=20+2-0.7=21.3V.
Now when the input is at its positive peak,the diode is off and the capacitor stays at the same...
The LC circuit should oscillate with its natural frequency in absence of any external agent and the energy is alternatively converted from electrical to magnetic.Suppose that i include a diode in this circuit that acts as a switch.Now the capacitor is completely discharged while diode in on...
