Question

Definition Definition Study of chemical reactions that result in the production of electrical energy. Electrochemistry focuses particularly on how chemical energy is converted into electrical energy and vice-versa. This energy is used in various kinds of cells, batteries, and appliances. Most electrochemical reactions involve oxidation and reduction.

Expert Solution

Hint :

Current density is referred to as the total amount of current which is flowing through one unit value of a cross-sectional area. If this is of uniform current flow, then the amount of current which is flowing through a specific conductor is the same at all points of the conductor, even if the conductor area differs.

Kirchhoff's first law or the junction law states that: the total current entering the junction is equal to the total current leaving the junction. This follows from the conservation of charge - charge cannot be created or destroyed. As a consequence, the charge entering the junction should equal the charge leaving the junction. The scenario below: 12 1₁ 13 follows Kirchhoff's junction rule violates Kirchhoff's junction rule as there is no outgoing current cannot determine whether it follows the junction rule or not without knowing the magnitude of the currents
