What type of transformer is it, if primary winding is 3 times than secondary winding, primary voltage is 220 V, secondary voltage ?
Calculate the number of turns in secondary winding if primary winding is 770 turns, current 6A,220V mains and secondary 110V.
If the ratio of primary winding to secondary winding in a transformer is 0.5, primary voltage is 220 V. find secondary V.
A transformer is used to play radio of 6 V. If the transformer is connected to 240 volt ac mains and the number of turns in it is 1000, Calculate the number of turns in secondary coil.
The number of turns in primary winding of a transformer is 150 times more than that in secondary winding. Calculate the input emf in primary winding if the emf generated in secondary is 220 V.
Find the output voltage of the transformer given in the diagram.
