Question

How do you find the current in an LC circuit?

Answer 1

Explanation:

LC Circuit:

1. A capacitor denoted by the letter $\mathrm{C}$ and an inductor denoted by the letter $L$ make up an$LC$ circuit, sometimes referred to as a tank circuit, a tuned circuit, or a resonant circuit.
2. These circuits are employed to produce signals at predetermined frequencies or to receive signals from more complicated signals at predetermined frequencies.
3. Basic electronic components known as$LC$circuits are used in a variety of electronic devices, especially radio equipment, where they are used in circuits including oscillators, filters, frequency mixers, and tuners.
4. The main objective of an$LC$ circuit is to oscillate with as minimal damping as possible.
5. An electronic circuit known as an $LC$ circuit is composed of a capacitor$\left(C\right)$ and an inductor$\left(L\right)$.
6. Both in this case are a component of the same circuit.

In series LC circuit:

1. The series$LC$ circuit architecture, as depicted in the circuit, connects the capacitor $C$ and inductor $L$in a single line.
2. The inductor $\left(L\right)$and capacitor$\left(C\right)$are both being driven by the same amount of current, which is flowing via the positive terminal of the $LC$ circuit $\left(C\right)$.
3. Circuit current in $LC$ series:$\mathrm{i}=i_L=i_C$

In parallel Lc circuit:

1. The parallel $LC$ circuit design, as shown in the circuit, connects the capacitor$C$ and inductor $L$in parallel.
2. The combined current flowing through the inductor $\left(L\right)$and capacitor equals the current flowing through the positive terminal of the $LC$ circuit $C$.
3. Circuit current $LC$ in parallel:$\mathrm{i}=i_L+i_C$

Hence,

The inductor $\left(L\right)$ and the capacitor $\left(C\right)$ are coupled in series in a series $LC$ circuit. The circuit's current flow is equivalent to the current that a series circuit would have with an inductor and capacitor.

Current in series $LC$ circuit, $I=I_L=I_C$.

The total current flowing through the inductor and capacitor together makes up the circuit current in a parallel $LC$ circuit.

Current in a parallel $LC$ circuit, $I=I_L+I_C$
