Transformers in Series, calculating the current

Click For Summary
SUMMARY

The discussion centers on calculating current in a transformer circuit using standard transformer equations, specifically the turns ratio (Vs/Vp = Ns/Np). The user reports using 4 amps for the secondary current but consistently arrives at an incorrect primary current of 1.6 amps. The mentor advises focusing on the two unknowns in the problem, indicating that a more systematic approach is necessary to solve for the primary current accurately.

PREREQUISITES
  • Understanding of transformer equations and principles
  • Familiarity with Ohm's Law
  • Basic knowledge of electrical circuits
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Study the relationship between primary and secondary currents in transformers
  • Learn how to apply Kirchhoff's laws in circuit analysis
  • Explore the concept of impedance in AC circuits
  • Review examples of transformer problems involving unknown variables
USEFUL FOR

Electrical engineering students, educators, and professionals seeking to deepen their understanding of transformer operation and current calculations.

I have been given the attached question by my mentor.

I have used the standard transformer equations (Vs/Vp=Ns/Np etc.) but I am struggling to work toward the right answer. I am using 4 amps for question A (standard ohms law) but don't think I am tackling this right. As for current in the primary I always seem to come up with 1.6 amps. My mentor has told me this is wrong and I should be looking at the two unknowns. I'm completey stuck!

Can anyone help?
