- Draw the graphs showing variation of Inductive reactance and Capacitive reactance with frequency of applied A. C source.
In the adjoining circuit, calculate the inductive reactance and the capacitive reactance What should be the source frequency so that the two reactance become equal in magnitude? What would then be the impedance (in ohms) of the circuit?
- In an AC circuit, a resistance of R ohm is connected in series with an inductance L. If phase angle between voltage and current be {45 . . . - Toppr
The resistance is of 16 Ω and for a given frequency, the inductive reactance of L is 24 Ω and capacitance reactance of C is 12 Ω If the current in the circuit is 5 A, find the potential difference across R, L and C in (V)
- Inductive reactance - Toppr
The inductive reactance of a coil is 1000 Ω If its self inductance and frequency both are increased two times, then inductive reactance will be
- Assertion : In series LCR circuit, the resonance occurs one frequency only. Reason : At resonance the inductive reactance is equal and . . . - Toppr
Assertion (A): In series LCR resonance circuit, the impedance is equal to the ohmic resistance Reason (R): At resonance, the inductive reactance is equal and opposite to the capacitive reactance
- Explain the term inductive reactance. - Toppr
explain inductive reactance show grapically variation of inductive reactance with frequency of applied alternative voltage b)at AC Voltage B=Vosinwt is applied across pure inductor find the expression of current show that current lags behind voltage by 90 degree
- Assertion :When capacitive reactance is smaller than the inductive reactance in - Toppr
Assertion :When capacitive reactance is smaller than the inductive reactance in L−C−R circuit, emf leads the current Reason: The phase angle is the angle between the alternating emf and alternating current of the circuit
- Show graphically the variation of inductive reactance with frequency of the applied alternating voltage.
Draw the graphs showing variation of inductive reactance and capacitive reactance with frequency of applied a c source
- Assertion :in series LCR resonance circuit, the impedance is equal to the ohmic resistance Reason: At resonance, the inductive reactance exceeds . . .
