Question

If a transformer primary is energized from a square wave voltage source, then its output voltage will be

Answer 1

A) A square wave. (B) A sine wave.
(C) A triangular wave. (D) A pulse wave

these are the options choose any one because I don't know what is answer but I have confident that any one is correct from this option so pls find which is correct ...... choose from these options because from this option any one is correct

Answer 2

Answer:

If the input to a power transformer is a square wave then the output voltage is a pulsed wave.

Explanation:

Power transformers have a threshold limit of frequency.

Square wave is mathematically equivalent to a sine wave plus odd multiple frequencies of sine wave with reducing amplitude.

If a transformer primary is energized from a square wave voltage source, then the higher frequencies beyond the limit of transformer are filtered.

Therefore, its output voltage will be a pulsed waveform.
