Consider Figs. 2(a) and 2(b). Do both figures show a current to the right?
Explain.
Homework Answers
As for convention - current flow in the direction where the positive chagre will flow or current flow oppsite to the direction of flow of negative charge.
In figure ( a) sphere has positive charge and it is moving to the right so current will also flow in right direction.
In Figure (b) sphere has negative charge and it is moving to the left , due to neagtive charge current will flow in opposite direction.
so in both figure current will flow in right direction.

Part A and B
Please show all of the steps
Analysis of Electroplating When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is...

Consider two positive charges separated by a distance ((A+20)/100) meters. One charge hasa value of (B+5) mC (milli-coulombs) and is located to the right of the other (C+ 5) mC charge. Assume the left charge is the origin and the other charge is located with a positive horizontal position. How large and in what direction is the electrostatic field at the mid-point, directly between the two charges? Use i-notation for the...

Learning Goal: To relate current, time, charge, and mass for electroplating calculations. Electroplating is a form of electrolysis in which a metal is deposited on the surface of another metal. To quantify electrolysis, use the following relationships. Electric current is measured in amperes (A), which expresses the amount of charge, in coulombs (C), that flows per second (s): 1 A 1 C/s Another unit of charge is the faraday (F),...
