Resonant Frequency:

A tank circuit refers to an LC circuit in which the inductor (L) is placed in parallel with the capacitor (C). Tank circuits are especially useful due to their property of carrying resonance, and are implemented in several electrical applications, such as filters, frequency tuners, and oscillators.

**Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
