Series & Parallel Resistors

Resistors in Series:-

Resistors are said to be connected in series when they are daisy chained together in a single line resulting in a common current flowing through them.

                       A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor.

Resistors in Parallel:-

                  A parallel circuit is a circuit in which the resistors are arranged with their heads connected together, and their tails connected together. The current in a parallel circuit breaks up, with some flowing along each parallel branch and re-combining when the branches meet again. The voltage across each resistor in parallel is the same.
