By ringing a bell whenever he gave food to his lab dogs, Pavlov eventually got the dogs to salivate to the sound of the bell. In this context the salivation elicited by sound of the bell is called the response.

Classical Conditioning

Explanation:

Salivating to food in the mouth is reflexive, so no learning is involved. The dogs' salivation was an unconditioned response (UCR).

Pavlov's theory  developed into classical conditioning, which refers to learning that associates an unconditioned stimulus that already results in a response (such as a reflex) with a new, conditioned stimulus. As a result, the new stimulus brings about the same response.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
