If an LC circuit is considered to be analogous to a harmonically oscillating spring block system, which energy of the LC circuit would be analogous to potential energy and which one would be analogous to kinetic energy?ДЄns. A superheterodyne receiver, which is often shortened to superhet, is a type of radio receiver which uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency. This is used in superheterodyne oscillators.ДЄns.

This makes the tuning of the receiver very simple. In modern days, the incoming frequency of a radio receiver is superposed with a locally produced frequency that produces an intermediate frequency and this is always constant. Therefore, the current starts oscillating instantaneously. In an ideal parallel LC circuit, the capacitor is charged by connecting it to a DC source that is then disconnected. As we know that the maximum current flows when the circuit is at resonance. The values of inductance and capacitance in an LC circuit are 0.5 H and 8 ОјF respectively and current in the circuit is maximum, then the angular frequency of alternating emf applied in the circuit will beДЄns. Sample Questions Very Short Answer Type Questions This oscillation of the energy between the LC circuit has been considered with some assumptions:В The energy loss in the circuit is neglected.The charge in the circuit oscillates with a natural frequency which has been derived by applying the KirchoffвЂ™s laws to the circuit and deriving the result to be: w=1в€љ(LC).This induced current in the circuit produces a magnetic field inside the inductor.

The capacitor is charged to its full capacity and now we connect it end to end to the inductor in the circuit.

The electrical charge stored in the capacitor is the initial charge on it which may be termed as q m.

Generally, charge as a function of time in simple harmonic motion will be given as: q(t)=Qo sin(П‰t+О¦).

When a charged capacitor is connected to an inductor in the circuit, the electric current in the circuit and the charge on the capacitor undergo oscillations which are known as LC Oscillations.

This is the current as a function of time. Now differentiating charge with respect to time will be, So, charge as a function of time will be, Generally, charge as a function of time in simple harmonic motion will be given asДЄs t = 0, q(0) = Q0, therefore, by putting this value in the above equation we get, Solution of Simple Harmonic Motion Equation
