Explain current divider rule Current flow through at every resistor that connected by parallel can be find by using current divider rules (CDR).
A 3-kVA, 220:110-V, 60-Hz, single-phase transformer yields these test data: • Open-circuit test: 200 V, 1.4 A, 50 W • Short-circuit test: 4.5 V, 13.64 A, 30 W Determine th
