what is parralal and series connection?

Hey aspirant,

In simplest terms, Parallel and series connection are the two simplest ways of connecting components like resistors, inductors, cell (battery) etc. in an electric circuit.

In a series circuit, components are connected along a single path of conduction, so the same current will flow across the circuit, but voltage is dropped across each resistor. Current I is same for all the elements, but voltages V1, V2,.... so on will vary.

A parallel circuit will have electrical components connected across parallel, in multiple paths, so current will split in each path, but voltage across resistors will remains same. In a parallel circuit, voltage V will remain the same, whereas current I will split into I1, I2,.... and so on.

In real-life application, parallel circuits are used in most of household electricial wiring, while series circuits are used in fuses and circuit breakers to protect electrical installations.

Hope this is helpful.

Hello there,

Basically Series and Parallel connection are two types of Electrical circuit connection,there is another one by name Series-Parallel connection.

Series Connection :

In Series connection resistors or loads are connected end to end so that the circuit will have only one path throughthe direction of current. Thus, when a number of resistors or loads are connected in series, the effective resistance is equal by adding the individual resistance algebraically.

Say, if we have resistors with resistance R1, R2, R3 …Rn connected in series , then,

R _eff = R ₁ + R ₂ + R ₃ + …R _n .

In series connections, the same current will flow across all the branches of the circuits, but different voltage as the resistors will have  different voltage across them and  Each resistor or load will experience a voltage drop.

Parallel Connection :

Resistors, loads are said to be connected in parallel when the end of each of the resistors or loads have a common point or junction and the other ends are also connected to a common point or junction. Such circuits are known as parallel circuits.

Say, if we have resistors with resistance R1, R2, R3 …Rn connected in parallel , then,

1/R _eff or 1/R _T = 1/R ₁ + 1/R ₂ + 1/R ₃ …1/R _n .

Parallel circuit connection have the same voltage flowing across all the branches of the circuit. Different resistors have their individual currents.

Feel free to ask ,if you want to know more.

Hope it Helps.
