What is half power frequencies?

The frequencies for which current in a series RLC (or a series tuned) circuit is equal to 1/√2 (i.e. 70.71%) of the maximum current (current at resonance)are known as Half Power Frequencies.

What is half power frequency formula?

At the half frequencies, power of the circuit is P=Pmax2=i2maxR2=(imax√2)2R. This means that the current in the circuit at half power frequencies is imax√2.

What is meant by half power points?

The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. In filters, optical filters, and electronic amplifiers, the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency.

What is upper half power frequency?

The upper half-power frequency of the series RLC circuit is given by: ωh = R 2 L + ( R 2 L ) 2 + 1 L C rad/sec. Where R is the resistance, L is the inductance and C is the capacitance of the series RLC network.
