For a science experiment you need to electroplate a 120-nm-thick zinc coating onto both sides of a very thin, 2.0 cm × 2.0 cm copper sheet. You know that the charge carriers in the ionic solution are divalent (charge 2e) zinc ions. The density of zinc is 7140 kg/m3. Part A If the electroplating apparatus operates at 2.0 mA , how long will it take the zinc to reach the desired thickness?

For a science experiment you need to electroplate zinc onto both sides of a very thin, 1.00 cm × 1.00 cm copper sheet. You want the zinc thickness to be 140 nm , and you know that the charge carriers in the ionic solution are divalent (charge 2e) zinc ions. The density of zinc is 7140 kg/m3 If the electroplating apparatus operates at 1.40 mA , how long will it take the zinc to reach the desired thickness?

a. A sculptor has asked you to help electroplate gold onto a brass statue. You know that the charge carriers in the ionic solution are singly ionized gold ions, and you've calculated that you must deposit 0.50 g of gold to reach the necessary thickness. How much current do you need, in mA, to plate the statue in 4.0 hours? b. A metallic wire has a diameter of 4.12mm. When the current in the wire is 8.00A, the drift velocity...
