Answer:

The current in the primary coil would be
$0.5\ A$ .

Step-by-step 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

P=V* I

Where,

is the power in Watts.

is the voltage in Volts.

is the current supply in Ampere.

$I=(P)/(V)\\\\I=(60)/(120)\\ \\I=0.5\ A$

So, the current in the primary coil would be
$0.5\ A$ .
