← ScienceWhich phenomenon inhibits induced current when rapidly switching inductive load?
A)Back EMF due to inductive reactance✓
B)Ohmic heating dissipating excess energy
C)Magnetic field saturation in the inductor
D)Increased dielectric breakdown susceptibility
💡 Explanation
Back EMF impedes current because a changing magnetic field induces a voltage opposing the initial current change due to Lenz's Law; therefore back EMF limits current, rather than increased heating which stabilizes steady-state operating temperature in a conductor.
