Electroplating is done for:
1). The replacement of worn out material
2). The protection of metals against corrosion
3). Giving a shining appearance to articles
4). All of the above
Electroplating is defined as the deposition of a metal over any metallic or non-metallic surfaces. Electroplating is usually employed
1. To protect the metals from corrosion by atmospheric air, moisture and CO2
2. To give the reflecting properties to reflectors
3. To replace worn out metals
4. To give a shiny appearance to articles1. Calculate the cutoff frequency of a first-order low-pass filter for R1 = 2.5kΩ and C1 = 0.05μF
3. To produce an 800 Hz sine wave, a four-pole generator must be operated at
4. In a capacitor the electric charge is stored in
5. Second-order determinants are evaluated by subtracting the signed cross-products.
6. The depletion layer width of Junction
7. Protection by fuses is generally not used beyond
8. Ageing of a selenium rectifier may change the output voltage by
9. Short-circuit test on an induction motor cannot be used to determine
