What is bandwidth formula?

Bandwidth is measured between the 0.707 current amplitude points. The 0.707 current points correspond to the half power points since P = I 2R , (0.707)2 = (0.5). Bandwidth, Δf is measured between the 70.7% amplitude points of series resonant circuit.

Is frequency range same as bandwidth?

Bandwidth is completely related to frequency but definitely, bandwidth is not frequency. However, bandwidth is the range of frequencies . Bandwidth is defined as the difference in the upper and lower frequency components present in a signal. Thus, it specifies the amount of data being transmitted per second.
