What is arguably the major disadvantage of a parallel circuit is that as you add more and more things in parallel, the current draw on the source goes up and up and up. If the source cannot supply the current that is "demanded" by the devices all strapped across the so-called "rails" of the circuit, the voltage will (must!) decrease. This could be very bad, as some devices, notably motors, don't like to run at low voltage and can actually be damaged if voltage sags too much and they don't have undervoltage protection. Fortunately, we have a pretty good power grid in many places, and this isn't a problem. Additionally, many devices have undervoltage protection built in, and they'll "trip" and shut down if voltages sag to a preset threshold.

Some disadvantages of parallel circuits include the complexity of wiring multiple components, the potential for unequal current distribution among components leading to power imbalances, and the increased cost due to needing separate connections for each component.

The current flowing through each branch may be same or different. But it is definitey less than the current flowing out from the source

What are the advantages and disadvantages of series circuits?

There are no particular advantages or disadvantages of series or parallel circuits. Some circuits require one while other circuits require the other. Frequency filters often require one or the other depending on whether you need a pass or rejection filter.


Can parallel circuits be used instead of fuses?

No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.

What is the name of the circuit that is neither parallel nor series?

FEEDBACK CIRCUITS. In addition to parallel and series circuits, there are also closed and short circuits.


Does a parallel circuit have more than 1 resistor?

Parallel circuits normally have more than one resistor. Basically parallel circuits are circuits where the current has more than path to follow. However, there are parallel circuits where there are two switches rather than two resistors.
