WebFeb 22, 2024 · Thus the transformer couldn’t be used for DC then. Construction of the Transformer Basically, a transformer is made up of two parts which include; two inductive coils and a laminated steel core. The coils are insulated from each other and also insulated to prevent contact with the core. WebWhen we apply DC voltage to the transformer, the reactance of its winding will be zero since reactance is frequency-dependent and the frequency of a DC supply is zero. The … WebTransformers do not pass direct current (DC), and can be used to take the DC voltage (the constant voltage) out of a signal while keeping the part that changes (the AC voltage).
