Transformer Formula Pdf. Line voltage or primary voltage is the voltage from the source. The efficiency of a transformer is the ratio of the power it delivers to the load to the power it absorbs from the supply.
Here are some important nec rules you need to know when working with high legs. The efficiency of a transformer is the ratio of the power it delivers to the load to the power it absorbs from the supply. Transformer calculations without x r and utility impedance choose from the drop down menue or fill in the blnk were required.
This works the same on the secondary.
