LUDO › Simulations › Alternating Current

Step Up

Step the voltage up or down. Send power down a long line with little loss.

Physics · Class 12 · Transformers and power lines · 6 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Step down: One changing flux through two coils
  2. Both currents: Power in = power out
  3. Size the load: The load decides the power
  4. A real transformer: A real transformer loses some power
  5. Raise the voltage: High voltage, low loss
  6. The town's step-down: The line takes some voltage
