Transformers In a certain transformer, the input power to the primary is 120 W. If 8.5 W are lost to the winding resistance, what is the output power to the load, neglecting any other issues? 14.1 W 111.5 W 0 W 1,020 W 14.1 W 111.5 W 0 W 1,020 W ANSWER DOWNLOAD EXAMIANS APP
Transformers The efficiency of a transformer, under heavy loads, is comparatively low because voltage drop both in primary and secondary becomes large iron loss is increased considerably copper loss becomes high in proportion to the output secondary output is much less as compared to primary input voltage drop both in primary and secondary becomes large iron loss is increased considerably copper loss becomes high in proportion to the output secondary output is much less as compared to primary input ANSWER DOWNLOAD EXAMIANS APP
