← TechnologyWhich consequence results when impedance lowers in an inductive circuit, specifically with an air circuit breaker?
A)Increased short circuit current✓
B)Decreased breaker tripping time
C)Reduced magnetic field strength
D)Enhanced voltage regulation stability
💡 Explanation
An impedance decrease during a fault causes increased current, which leads to increased *electromagnetic induction*. Thus, the breaker detects this and trips due to overcurrent, because a high fault current has a lower impedance fault path therefore higher potential damage, rather than providing stable voltage.
