In an ideal step-up transformer input voltage is 110V and current flowing in the secondary is 10A, if transformation ratio is 10, calculate output voltage, current in primary input power and output power.
Open in App
In step-up transformer, transformation ratio (K>1)=N2N1=V2V1=I1I2=10(Given)eq....1
Now, using eq.1, V2110=I110=10(Given)
And, Input power = Output power = V1I1=110×100=11kW
Therefore, output voltage, current in primary ,input power and output power is 110V,100A,11kW,11kW respectively.
