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.
Electric current is defined as the rate at which charge flows through a surface (the cross section of a wire, for example).Despite referring to many different things, the word current is often used by itself instead of the longer, more formal electric current.his means that the coulomb is defined as the amount of charge that passes through a surface when a current of one ampere ampÃ¨re flows for one. [Second = C]. As When i visualize, Current i see things. Moving i see them moving in a. direction
