Answer:

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

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\times I

Where,

P is the power in Watts.

V is the voltage in Volts.

I is the current supply in Ampere.

I=\frac{P}{V}\\\\I=\frac{60}{120}\\ \\I=0.5\ A

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

What is the benefit of developing the atomic mass unit as a standard unit of mass?
Alexeev081 [22]

Answer:

The atomic mass unit is 1/12 of an atom of carbon 12, and is a very small amount to represent in kilograms:

1m_{u}=1.66054x10^{-27}kg

m_{u} is atomic mass unit.

This is why the benefits of the atomic mass unit is that it makes the representation of atomic masses easier in terms of the simplicity of the numbers that are used to represent the masses. Also using the atomic mass unit it is easier to compare the masses of different atoms, These numbers would be very small and would require negative powers of 10 to represent them, so it is more convenient to use the atomic mass unit.
