When associated in a series, contents are i ordered it one after the various other like train cars. The battery drives current through the series circuit, which is a close up door loop, therefore the present must be the same through each resistor.

You are watching: What are the advantage of a parallel circuit?


Think the the battery together a pump station, current as water and the resistors as houses. This circuit is choose a ar where water is pumped v all the houses sequentially until ultimately returning to the pump station. In this case, the very same amount that water must circulation through each house.


If present is the same through every the resistors in series, Ohm’s law shows the voltage across an individual component might vary, relying on its resistance.


In contrast, in a parallel circuit, resistors or gadgets are connected like the rungs that a ladder. A parallel circuit is favor a ar where each residence is top top its very own branch the the water line and may attract a different amount of water there is no affecting the others.


Ohm’s law, to express to calculation current, is: ​I = V/R​. Once parallel resistors are connected to a voltage supply, each component has actually the same voltage across it yet may draw differing current, again depending on the individual resistance.


A series collection the resistors R1, R2, R3, . . . Is tantamount to a single resistor, Rs, same to the amount of every the resistances:


Resistors R1, R2, R3, . . . In parallel additionally act together a single resistor, but the calculation of equivalent resistance Rp is an ext complicated, offered by:


Adding a resistor in parallel come a circuit constantly ​decreases​ the equivalent resistance. This connection has amazing implications in determining the disadvantages or advantages of a parallel circuit.


The defect or benefits of a parallel mix of facets depends on the situation. Houses, for example, are wired therefore electrical gadgets may be provided in parallel. When a refrigerator is plugged right into a kitchen outlet, it consumes electrical energy without affecting voltage or current in the rest of the residence – and therefore go not impact the operation of any kind of other appliance. This is among the benefits of a parallel connection.


The bulbs top top a wire of modern-day Christmas lights are also connected in parallel. If one pear burns out, it becomes an open up circuit the doesn"t influence the other bulbs. The rest of the string continues to be illuminated. Due to the fact that the single dark pear is automatically obvious, it can be easily found and replaced – again an advantage of a parallel circuit.


Old-style Christmas lamp were associated in series, and also a burnt-out pear stopped existing through the entire string, shutting off all the lights. Imagine how difficult it would be to discover the one negative bulb!


The disadvantage that a parallel link becomes apparent with a brief circuit, together as once someone jams a wire between the two contacts that an electrical outlet. A short circuit has very low resistance, i m sorry in turn causes current in the circuit to rise tremendously, and bang! Sparks fly and also the wiring heats, possibly leading to a fire.

Fortunately, the fuse blows and becomes an open circuit. Due to the fact that it is in collection with the wiring, the fuse does its job and also stops the present flow prior to anything can be damaged.
