- State whether True or False:
A Series resonant circuit is commonly called a tank circuit.
A) True
B) False

Hint: An LC circuit is also called a tank circuit is an inductor and a capacitor connected together. LC circuits are used for generating signals at a particular frequency from a computer signal.

Complete step by step answer:
As of Tank Circuit an older name is tank circuit because its operation is analogous to a tank to a fluid system, in which the dimensions of the tank define the natural frequency observed when the fluid is pulsed through the tank. Resonance occurs in a series circuit when the supply frequency causes the voltages across $L$ and $C$ to be equal and opposite in phase.
An $LC$ circuit is also called a tank circuit is an electric circuit consisting of an inductor and a capacitor connected together $LC$ circuits are used for generating signals at a particular frequency from a computer signal.
Series resonance circuits are one of the most important circuits used in electronic circuits. They can be found in various forms such as in AC mains filters, noise filters and also in radio and television tuning circuits for the receiving of the different frequency channels.

From the above explanation we can say that The statement is TRUE

Note:
Series resonance RLC circuit is called a voltage magnification circuit, because the magnitude of voltage across the inductor and the capacitors is equal to $Q$ times the input sinusoidal voltage $(v)$.
The dimensions of the tank define the natural frequency observed when the fluid is pulsed through the tank.
