Question

6. In electric arc furnace Cu or Iron is melted due to variation of
(a) current (b) magnetic field ( voltage (d) electric field​

Answer 1

Answer:

In electric furnace Cu and Fe is melted due to variation of current.because current generates heat and electricity

Answer 2

In electric arc furnaces, Cu or Iron can be melted due to the variation of Current.

• An electric arc furnace can be defined as a high-temperature furnace that uses high-voltage currents as a primary heating element.

• With the use of electric arc furnace steel can be made from a 100% scrap metal feedstock.

• These furnaces are very flexible.

• Cu or Iron can be melted in the furnaces with the variation of high-voltage currents.
