# What is a Series Circuit?

## Series Circuit

Basically this circuit consists of a series of elements connected one after the other. And it is also called one to one connection or cascade connection. A circuit short in series or a break at any point in the circuit causes the entire circuit to become unusable. The total voltage applied to a series circuit is distributed in a series of voltage drops across the various components of the circuit. In other words, the sum of the voltage drops across the individual components in a series circuit equals the total applied voltage. [ Vt = V1 + V2 + V3…+Vn ]. There is only one path available for current flow in this circuit and the current through all the elements in a series circuit is the same. [ It = I1 = I2 =I3 … = In ]. Basically in a resistive series circuit, the total resistance is equal to the sum of the individual resistances. [ Rt =  R1 + R2 + R3…+Rn ]. In an inductive series circuit, the total inductance is equal to the sum of the individual inductances. [ Lt =  L1 + L2 + L3…+Ln]. and capacitive series circuits, the total capacitance is less than any individual capacitance. [ Ct = 1 / (1/C1 + 1/C2+ . . . 1/Cn)]. Components with different current ratings cannot be connected in a parallel circuit. Basically this circuit is used to protect the circuit while connecting fuses and circuit breakers to other devices. A series connection of light bulbs is very useful if you have low voltage bulbs to run from very high voltages.
