सूत्र
## Transformer A transformer transfers electrical energy between circuits via magnetic coupling, changing voltage and current levels. ### Formulas **V2 / V1 = N2 / N1** (voltage ratio equals turns ratio) **I2 / I1 = N1 / N2** (current ratio is inverse of turns ratio) Power is conserved in an ideal transformer: P1 = P2.
हल किया गया उदाहरण
A step-down transformer: 120 V input, 500 primary turns, 50 secondary turns, 1 A primary current.
- 01Turns ratio = N2/N1 = 50/500 = 0.1
- 02V2 = V1 * N2/N1 = 120 * 0.1 = 12 V
- 03I2 = I1 * N1/N2 = 1 * 500/50 = 10 A
- 04Power check: 120*1 = 12*10 = 120 W
अक्सर पूछे जाने वाले प्रश्न
Can a transformer work with DC?
No. Transformers require a changing magnetic field to operate, which means they only work with AC (alternating current).
What is a step-down transformer?
A transformer with fewer secondary turns than primary, producing a lower output voltage. A step-up transformer does the opposite.
Why are transformers not 100% efficient?
Real transformers have losses from wire resistance (copper losses), magnetic hysteresis, and eddy currents in the core (iron losses).
