← ScienceWhich mechanism reduces capacitive reactance in AC circuits?
A)Dielectric polarization response lag✓
B)Increased dielectric breakdown strength
C)Decreased conductor surface roughness
D)Spontaneous electron tunneling effect
💡 Explanation
Capacitive reactance decreases with increasing frequency; it is reduced through dielectric polarization. The polarization response lags the applied voltage because dipole alignment takes time within the dielectric, therefore limiting charge storage, rather than breakdown or roughness changes at higher frequency.
