Technology

Which 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.
