what is series in electric circuit?
In a series connection, all the components of the electrical circuit are connected end to end (lengthwise) with each other. In such connections, the total resistance of the circuit increases.The equivalent resistance of the all the components connected in series is given by the algebraic sum of their individual resistances.
Equivalent resistance or Rs = R1 + R2 + R3 + …
In this type of connection, the current is same through the whole circuit having different components whereas, there is a different voltage drop across each component depending upon its resistance.
