Question

What is the difference between RC and LC filters?

Answer 1

Hint: In this question, we need to describe the difference between RC and LC filters. We can say that for weak signal filtration, RC is enough whereas, for filtering high-power signals, LC works well.

Complete step by step solution:
Let us discuss the differences between RC and LC filters.

RC Filters	LC Filters
They are suitable for filtration of low power signals current.	They are suitable for filtering high-power signals.
The RC circuit is a series combination of resistance and capacitance that saves energy in the form of an electric field	The LC circuit is a series combination of resistance and inductance that saves energy in the form of a magnetic field.
They created little or no noise.	It is made up of inductors that form a magnetic field that causes hysteresis as well as noise in the circuit.
They are small in size, lightweight, and inexpensive.	As inductors are huge in size, RL filters are massive and costly.
The RC filter consumes more power.	The LC filter consumes less power.
It needs ventilation to remove the heat generated by the resistor.	It does not require ventilation as heat is not generated in the inductor.

Therefore, the differences between RC and LC filters are mentioned above in tabular form .

Note: Here, we can say that the RL and RC circuits form the foundation of many electronic systems. Both have advantages and limitations; whatever circuit is utilized is determined by the application.
