Question

An LRC resonant circuit is often called an oscillator circuit. What is it that oscillates?

Answer 1

Answer with explanation: A RLC circuit is a type of electronic circuit arrangement that has three components or elements in it, there are as follows:

`\begin{gathered} R\Rightarrow\text{ Resistance} \\ L\Rightarrow\text{ Inductance} \\ C\Rightarrow\text{ Capacitance} \end{gathered}`

The order in which these components can be placed in a circuit can be any combination of the three, the RLC circuit diagram is shown below:

Finally, in the RLC circuit, the current equation is as follows, from this equation of current we can infer that the behavior of the current in the circuit is repeating, therefore oscillatory. In simple words current oscillates in the RLC circuit.

`I(t)=I_m\sin (wt)`
