What happens if frequency is lower than resonance?

What happens if frequency is lower than resonance?

At frequencies lower than the resonance frequency, the capacitor tends to dominate and the voltage lags the current; at higher frequencies the inductor tends to dominate and the voltage leads the current. The resonance frequency is about 1300 Hz.

When resonant frequency for an RLC parallel circuit is given by the essential condition is that?

When resonant frequency of an RLC parallel circuit is given by 1/2π√(LC), the essential condition is that. (a) impedance must be non-resistive.

Why does current decrease as frequency increases?

In an inductive circuit, as the frequency increases, the impedance also increases, so the current will be reduced. In a capacitive circuit, as the frequency increases, the impedance decreases, so the current will be increased.

How does current affect frequency?

As frequency increases, current tends to flow along the surface of a conductor. This is called ‘the skin effect’. The higher the frequency, the more pronounced this effect.

When resonant frequency for an RLC parallel circuit is given by?

We now know that at the resonant frequency, ƒr the admittance of the circuit is at its minimum and is equal to the conductance, G given by 1/R because in a parallel resonance circuit the imaginary part of admittance, i.e. the susceptance, B is zero because BL = BC as shown.

How does frequency affect the response of an RLC circuit?

When we change from lower to higher frequency through this point, the circuit changes from capacitive to inductive, or vice versa. Response depends upon whether RLC components are in series or parallel. In either case, impedance of the circuit varies with frequency.

Why is the current maximum in LCR circuit?

The Value of X [C] is negative; Hence at some specific frequency called Resonance X [L] + X [C] = 0 and and only R remains and hence the current will be maximum In LCR Circuit The resistor is not frequency dependent. It will behave same for AC or DC The L and C are frequency dependent .

What is resonance in RLC circuit?

Resonance in AC circuits is analogous to mechanical resonance, where resonance is defined to be a forced oscillation—in this case, forced by the voltage source—at the natural frequency of the system. The receiver in a radio is an RLC circuit that oscillates best at its .

What is the relationship between frequency and current in alcr circuit?

The reactance of a capacitor or an inductor present in aLCR circuit ,varies with frequency. If the reactance varies with frequency,then the impedance of the circuitalso changes. If the impedance of the circuit changes, then the current in the circuit also changes.
