Question

We are studying the corrosion rate between a piece of copper and a piece of zinc by dipping them in water and using a DMM to measure the conductivity. In the first test electric potential was found, then the electrical current was found. My question is how to find corrosion rate? Given the equation Nzinc= I / 2(96485.33), I being the electrical current in amperes. I just want to know really if the information we obtained is enough, maybe could you work it out using theoretical value. potential= 1 volt and current= 0.2 amps?

Please show work,

Thanks

answer:-

1. Voltages are two types by natural world. AC and DC voltages. To distinguish two unlike symbols are used. for dc electrical power, a solid row over V is second-hand. It represent DC electrical energy.
2. As AC stand for irregular current, AC voltages, are veries with occasion. These are represent sinusoidal (wavy line) symbol . It represent AC signal.
3. Mascot bent sign on the call place for ohmic sign. It is call as ohms. It is the unit of confrontation. It events confrontation of a cable or guide.
4. A place for amperes in the call.
5. A is have dissimilar setting with dissimilar variety of current to be on purpose. for example 2A variety can be used to gauge the present up to 2A.(utmost). If present exceed the known variety location can be distorted to next senior variety.
6. The function of the fatal labeled COM is ordinary fatal for all capacity.
7. Another people first name intended for this COM fatal port is earth or unbiased.
