Answer:
Transformers use “electrical steel” alloys. ... From 1% to 6.5% silicon is added, as well as a small amount (up to 0.5%) of manganese and aluminum to reduce brittleness in alloys with higher percentages of silicon. Electrical steels are formulated and processed to have low hysteresis and eddy-current losses.
Explanation:
The eddy currents consume energy and heat the iron core. The designers of the electrical machines and transformers laminate the core with thin sheets of iron coated with a thin oxide layer.

Answer:
2.Scientists discovered new evidence to support their theories.
3.Scientists discovered that old interpretations of data was incorrect.
4.Scientists used observations and mathematical data to solve problems in new ways.
Explanation: Here you go
If a point has 40 J of energy and the electric potential is 8 V, the charge must be: A. 5 C
<u>Given the following the details;</u>
- Electric potential = 8 Volts
To find the quantity of charge;
Mathematically, the quantity of charge with respect to electric potential is given by the formula;
Substituting the values into the formula, we have;
<em>Quantity of charge = 5 Coulombs</em>
Therefore, the quantity of charge must be <em>5 Coulombs.</em>
