Question

at 1800rpm, 1000, 12.5A efficiency of 80%, please find power factor, phase difference and output torque. No. 4 (3 points) For a multiple secondary transformer, R1, R2 and R3 are loads to the 3 secondary windings (with n1, n2, n3 turns). Primary winding has n0 turns. Derive the relationship of equivalent primary resistance R with R1, R2 and R3.

Step 1

In this context, R1, R2, and R3 are likely to be resistors connected in parallel. When resistors are connected in parallel, the total resistance (R) can be calculated using the formula: 1/R = 1/R1 + 1/R2 + 1/R3 Show more…
