The current in the primary coil would be .
Explanation:
Given the power supplied by a transformer is 60 watts.
And the voltage in the primary coil is 120 Volts.
We need to find the current supply in the primary coil.
We will use the formula
Where,
is the power in Watts.
is the voltage in Volts.
is the current supply in Ampere.
So, the current in the primary coil would be .
