What is the role of the counter electrode? Can we use the silver plate as a counter electrode and why?

1. An aluminum nail has an excess charge of 3.1 µC (3.1 × 10-6 C). How many electrons must be added to the nail to make it electrically neutral? qe = 1.6 × 10-19 C.

6.) Why are metals typically good electrical conductors? a. Metals have excellent insulator properties related to conductivity. b. Metals have electrons that can carry both the positive and negative charges needed to make electricity. c. Metals have electrons that can flow easily within the metal.

4. What does Ohm's law state? what are the differences between an Ohmic resistance and Non-Ohmic resistance? Explain the difference between Forward and Reverse Bias in a Diode. Then, write down Kirchoff's laws. Draw an example of a circuit that has both scries and parallel resistors. Determine the equivalent resistance from there.
