THE POLARITY MARKINGS ON TWO WINDINGS MUST BE DETERMINED EXPERIMENTALLY. THE DEVICE FOR SUCH DETERMINATION IS SHOWN IN THE FIGURE BELOW. THAT THE TERMINAL CONNECTED TO THE POSITIVE TERMINAL OF THE BATTERY RESERVES THE POLARITY MARKING AS SHOWN IN THE FIGURE. WHEN THE SWITCH IS OPEN, THE DC VOLTMETER UNDERGOES A NEGATIVE DEFLECTION. WHERE ON THE CONNECTED WINDING SHOULD A POLARITY MARKING BE ATTACHED TO THE VOLTMETER? t = 0 R )cc VOLTIMETER VB- CHOOSE AN OPTION BELOW: A. POINT AT THE LOWER END OF THE INDUCTOR B. POINT AT THE TOP END OF THE INDUCTOR C. NONE OF THE OPTIONS D. A DOT AT THE TOP END AND BOTTOM END C E. THERE IS NO COUPLING BETWEEN THE INDUCTORS, SO IT IS NOT NECESSARY TO PLACE A DOT

Three-Phase Transformers

Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.

Transformer

Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
