← ScienceWhich distortion arises when the electrical grid experiences harmonics?
A)Reactive power increases dramatically✓
B)Dielectric strength begins improvement
C)Impedance matching becomes optimal
D)Capacitance values remain unchanged
💡 Explanation
Harmonics in the grid cause increased reactive power because harmonic distortion increases the RMS current and voltage that are out of phase; therefore, reactive power rises, rather than optimizing impedance, strengthening dielectrics, or leaving capacitance unharmed.
