Question : 123 of 200

Marks: +1, -0

To a highly inductive circuit a small capacitance is added in series. the angle between voltage and current and current will___.

Solution:

For a highly inductive circuit, current flow through inductor lag with voltage

if small capacitor added in circuit, then capacitor supply lagging reactive power and phase angle between voltage and current decrease.

[ϕ_2<ϕ_1] ↑ \cosϕ=R/{(√ {R^2+{(X_L-X_C)^2}} )↓}
