How do you connect a diode across a ac coil?
You mean ac coil, the secondary coil, of a transformer? Then for the purpose of rectification, that is , for changing ac into dc, a diode is connected in series with the secondary coil of the transformer.
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
What are common efficiencies for transformers?
Transformer utilization factor is the ration of power delivered to the load and ac rating of the transformer secondary.
Why ac current is used in a transformer?
AC current or DC current can be used in transformers. A transformer is made of two coils of wire, the input coil induces a current into the output coil. Transformers change the voltage either up (step up transformer) or down (step down transformer). The amount of change in voltage is dependent solely on the number of windings in both coils in the transformer. DC transformers work exactly the same way AC transformers do.
