biological species concept. Members of the same species are capable of interbreeding, producing viable offspring, and cannot produce viable offspring with members of other species. This is one of several concepts that define a species, and is the most commonly used and accepted of those concepts.he most common method for species differentiation is the biological species concept, which defines a species as a population of organisms that can interbreed to produce viable, fertile offspring.
Electric current definition. Electrical current is the flow rate of electric charge in electric field, usually in electrical circuit. Using water pipe analogy, we can visualize the electrical current as water current that flows in a pipe. The electrical current is measured in ampere (amp) unit.
Electrical energy is energy stored in a charged particle within an electric field. Electric fields are areas surrounding a charged particle that exert a force on another charged particle within the field. Electrical energy is a type of potential energy, or energy stored in an object due to the position of the object. In the case of electrical energy, the object is the charged particle, and the position is within the electric field.
