How does the current in the secondary of a transformer compare with the current in the primary when the secondary voltage is twice the primary voltage?
To calculate: the current in the secondary coil of transformer when the secondary voltage is twice the primary voltage.
Answer to Problem 44A
The current would be
Explanation of Solution
Introduction:
The power input should be equal to the power output.
The power of the transformer is given as :
Here,
As the power of the transformer will be same so as the voltage become twice the primary voltage, the current would be 2 times less in the secondary coil.
Conclusion:
As the voltage increases in the secondary coil, the current will be reduced to equalize the power.
