Calculates transformer voltage and current relationships for different turns ratios. Essential for voltage conversion and impedance matching.
الصيغة
Turns ratio = secondary turns ÷ primary turns
دليل خطوة بخطوة
- 1Turns ratio = secondary turns ÷ primary turns
- 2Secondary voltage = primary × turns ratio
- 3Secondary current = primary ÷ turns ratio
- 4Power in ≈ power out (ideal)
- 5Account for losses (92-98% efficiency)
أمثلة محلولة
الإدخال
Vp=120V, Ns/Np=1/10
النتيجة
Vs=12V
أخطاء شائعة يجب تجنبها
- ✕Not accounting for transformer losses
- ✕Assuming ideal 100% efficiency
أسئلة شائعة
What's step-up vs. step-down transformer?
Step-up increases voltage, decreases current; step-down does opposite.
Why use transformers?
Voltage conversion, impedance matching, isolation, and distribution efficiency.
