The output power in step-up transformer used in practice is
The output power in step-up transformer used in practice is
- A. Greater than the input power
- B. Equal to the input power
- C. Less than the input power
- D. None of the above
Step-by-step solution
In practice, transformers have losses such as copper losses (I²R in windings), core losses (hysteresis and eddy currents), and leakage flux. These losses cause the output power to be less than the input power, unlike the ideal case where they are equal.
