What is the maximum value of power factor in LCR circuit?
Answer: The maximum value of power factor in alternating current LCR circuit can be 1 when the overall phase angle is zero, when the circuit achieves condition of resonance that is when the capacitive reactance becomes equal to capacitive inductance and the net impedance becomes vectorally parallel to the Voltage.
What is the power factor of a LCR circuit What are its maximum and minimum value and under what condition?
The minimum value of power factor is zero. It occurs in a purely inductive circuit. The maximum value of power factor is one.
What are the maximum and minimum possible values of the power factor for an AC circuit?
In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. The power factor can get values in the range from 0 to 1. When all the power is reactive power with no real power (usually inductive load) – the power factor is 0.
What is the maximum value of the power factor?
1.00
The maximum possible power factor is 1.00, which means that 100\% of the power delivered to the load is the active power converted into useful energy. Any value less than 1.00 indicates that the load supply system must be oversized.
What is minimum power factor?
Minimum power factor is 0 when R=0 i.e. when circuit is purely inductive or capacitive.
What is the maximum value of power factor Mcq?
Explanation: The maximum value of power factor is 1.
What is the minimum value of PF?
Employer’s Contribution towards EPF The minimum amount of contribution to be made by the employer is set at a rate of 12\% of Rs. 15,000 (although they can voluntarily contribute more). This amount equals Rs. 1,800 per month.
What is power factor of an LCR circuit?
The power factor of an LCR circuit is the ratio of the resistance to the total impedance of the circuit. The total impedance consists of the magnitude of the phasor sum of the resistance, the capacitive reactance and the inductive reactance. Therefore, the power factor of an LCR circuit at resonance is 1.
