Energy Stored in LC Circuit
In an LC circuit, energy is stored in two forms: magnetic energy in the inductor’s magnetic field and electric energy in the capacitor’s electric field. This energy oscillates back and forth between the electric and magnetic fields as the current and voltage oscillate. At any given moment, the total energy in the circuit is the sum of the energy stored in the inductor and the energy stored in the capacitor, and it is always constant.
The energy stored in an LC circuit, which consists of a capacitor (C) and an inductor (L), is given by the formula:
E= q2/2C + 1/2 LI2
Where,
- E is the Total energy stored in the circuit in joules (J)
- q2/2C is the energy stored in the capacitor
- 1/2 LI2 is the energy stored in the inductor
- q is the charge on the surface of capacitor
- C is the capacitance of the capacitor
- L is the inductance of the inductor in henries (H)
- I is the current flowing through the circuit in amperes (A)
Note: Total Energy in any LC Oscillation Circuit remains contstant.
LC Circuits
LC Circuit is a special type of electric circuit that is made up of an Inductor and a Capacitor. The inductor is represented by using the symbol L whereas the capacitor is represented using the symbol C. Hence, the name LC Circuit. LC Circuit acts as a major electric component in various devices such as oscillators, tuners, and filters. Thus LC circuit finds a number of applications in daily life. In this article, we shall discuss the LC circuit in detail.
