Question

metal coating during electroplating depends on
1. duration of current passage
2.a low current
3. nature of cathode
4. purity of anode​

Answer 1

Answer:

it will be option 2. A low current

Explanation:

a low current and for a longer time should be used for electroplating

As higher current causes uneven deposition of the metal.

Low current for a longer time initiates a smooth,firm,uniform & long lasting deposition.

Answer 2

Option 2 Metal coating during electroplating depends on low current

Electroplating is the process that uses an electrical signal from an external source to remove cation.

Explanation:

• Electroplating is the transfer of metal ions via a solution from a positive electrode to a negative electrode.
• Electric current is passed through the solution which causes objects at the cathode to be coated with the metal present in the solution.
• Metal coating during electroplating depends on low current
• So the correct answer is Option 2
