Question
Download Solution PDFA coil of inductance 10 H and resistance 40 ohm is connected in series with a capacitance and supplied by a source of variable frequency. If the maximum current is found at frequency 1000 rad/sec, then Q-factor of the circuit will be _______.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFQuality factor: The ratio of reactance and resistance gives the quality factor of a circuit.
\(QF={X_L\over R}={ω L\over R}\)
where, ω = Angular frequency
L = Inductance
R = Resistance
Calculation
Given, L = 10 H
R = 40 Ω
ω = 1000 rad/sec
\(QF={1000\times 10\over 40}\)
QF = 250
