What are the disadvantages of using a parallel circuit?

Answer 1

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.

Answer 2

Parallel circuit is basically very helpful to us.One disadvantage may be it requires wiring more ,as a result expenditure is also little bit high than that of series

------------------------------------

There's no real disadvantage. Series and parallel circuits serve different purposes.

A parallel circuit is necessary when you want all loads of the circuit to receive the same voltage--like lights and receptacles in a house.

A series circuit is necessary if you want to change the voltage a load receives. Loads in series will receive different voltages depending on their resistance and ampere draw.

Answer 3

There are three disadvantages of parallel circuits. These include the fact that they have complex resistance, voltage that is limited, and a current that varies.

Answer 4

parallel circuits are unable to bear over voltages

Answer 5

A: none
