Teaching UP B.Ed (Paper 1 & 2) Mock Test 2025 Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
In a series LCR circuit, the inductive reactance (XL) is 10 Ω and the capacitive reactance (XC) is 4 Ω. The resistance (R) in the circuit is 6 Ω.
The power factor of the circuit is :
1
\(\frac{1}{\sqrt{2}}\)
2
\(\frac{\sqrt{3}}{2}\)
3
\(\frac{1}{2}\)
4
\(\frac{1}{2 \sqrt{2}}\)
