Question 1
A circuit has R = 6 Ω, L = 0.15 H, and C = 80 µF. What is the phase angle at 50 Hz? Discuss its implications on circuit current.
💡 Hint: Calculate XL = ωL and XC = 1/(ωC) first.
Question 2
In a specific LCR circuit, if the phase angle is 45 degrees, derive the values of XL and XC when R = 5 Ω. Explain the significance of this angle in terms of circuit performance.
💡 Hint: Use tan(ϕ) relations to express XL in terms of XC.
