A transformer supplies 60 watts of power to a device that is rated at 20 volts. The primary coil is connected to a 120-volt ac source. What is the current I1I1I_1 in the primary coil

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 .

grav potential energy

im sorry i dont know
