A step-down transformer can step down the input voltage down to a lower voltage. Imagine a step-down transformer whose input is 2.5-kV supplies a load with 80 A. The primary winding is N1, the secondary winding is N2, and the ratio N1/N2 is 20. Calculate the power output in kW.
Load is connected in the secondary part (output). And so, given
the applied voltage in the primary part (input)
And the winding ratio
The voltage in the secondary unit (output) is
And given the electric current in the load (output)
The power output is
