167. If the primary winding of a particular voltage transformer rated for a given AC input voltage is mistakenly connected to a comparable steady DC input voltage with similar source impedance, selfinductance and mutual inductance are not possible. As a result, what part of the transformer will result in current overload?
Applying DC to a transformer's primary winding eliminates inductive reactance, causing the winding to behave as a low-resistance conductor and draw excessive current, leading to overload.
