Business Studies class 12 notes are prepared by the subject experts who have experience of over 20+ years and sound knowledge of the latest CBSE syllabus as well as the Class 12 board exam pattern. Quality factor is expressed as, Q-factor is a dimensionless quantity. The concept of Q, Quality Factor was first envisaged by an engineer named K. S. Johnson from the Engineering Department of the Western Electric Company in the US. In an AC … Quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation. Mon to Sat - 10 AM to 7 PM Capacitance It is defined as the peak energy stored in the circuit divided by the average energy dissipated in it per radian at resonance. Frequency of the supply, v = 12 kHz = 12 × 10 3 Hz Angular Frequency,ω = 2 πv= 2 × π × 12 × 10 3 03 = 24π × 10 3 rad/s Peak voltage, Maximum current, For an RC circuit, the voltage lags behind the current by a phase angle of Φ given as: Hence, Φ tends to become zero at high frequencies. Any resistance will reduce the overall inductor Q factor. View solution In the L C R circuit shown in Fig., the ac driving voltage is V = V m sin ω t . Quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation. Q (quality factor)는 총 에너지 손실 합에 대한 캐패시터나 인덕터같은 리액티브 소자에 축적된 에너지의 비이다. what is the definition of quality factor. The Q factor of an RF resonant circuit is given as: \(Q=\frac{F_{0}}{F_{3dB}}\) Inductor Q factor basics. When a current-carrying coil is placed in a magnetic field, it experiences torque. 1.Phasor The representation of AC current and voltage by rotating vectors is calle^ phasor and the diagram representing these phasors is known as phasor diagram. This would create inability in learners‟ lives and compromise their overall experience of living socially, culturally and economically. text-transform: none;
