1/27/2024 0 Comments Parallel circuit definitionLots of wires are required – lots of wires are required in the construction of a parallel circuit, this can make parallel circuits look messy if they are not wired neatly.Below we have listed some of the most common disadvantages associated with parallel circuits: Like anything, parallel circuits can come with some disadvantages. What are the disadvantages of using a parallel circuit? This is great for circuits that feature a number of components such as lighting circuits as they can still provide light if one fails. If a fault occurs current can still pass using different paths – when a component or wire fails in a parallel circuit current can still flow through different branches.Connecting or disconnecting components without affecting the circuit is possible – when you connect or disconnect new components or appliances in a parallel circuit it will not affect the other components or circuit.Equal voltage is shared across all components – because voltage remains consistent in a parallel circuit we know that each component shares the same level of voltage.We have listed some of the key benefits below: Using a parallel circuit over a series circuit can offer some advantages, parallel circuits are used in a number of applications due to the benefits they can offer. What are the advantages of using a parallel circuit? The current would still divide between the components (although it would be different readings) and added together again before the cell. If however, the resistance was different on the lamps the current readings would not match, the higher resistance of a component the lower the current. If you look at the image below you can see that the current is shared between the bulbs, then on the final branch of the circuit it would return to its full level. The current is shared between each branch and then is added together again when it meets before the power source. What Happens to Current in a Parallel Circuit?Ĭurrent is shared in parallel circuits, for example, if a circuit had 2 lamps (both with the same resistance) and a supply of 10 Amps they would both have 5 Amps going through them. Also if you add more lights to the circuit the others still stay bright as the current is shared. This means if a bulb fails the other lights in the circuit continue to work and stay illuminated, unlike a series circuit. We use parallel circuits in our houses/offices for lighting circuits. This is why we choose parallel circuits for some applications and why they are used over series circuits for some electrical equipment/systems. If a component fails or is disconnected the other branches still supply voltage/ current to the other components and keep them functioning. Parallel circuits can be very complex and include a lot of different components and branches. The image above shows a very basic parallel circuit with only a cell and two bulbs used in it. To pass through every component in the circuit then you would have to travel down each branch. If one of the bulbs fails in the circuit then current will still be supplied to the other bulb. If you look at the image below you can see that there are two different branches for the electrons to flow through. If one light fails the others in the same circuit will still be able to operate. Lighting circuits are one of the most common places where you will find parallel circuits. Regardless of how many branches that exist in a parallel circuit there are never more than two sets of electrically common points. In a parallel circuit if one component fails the electrical circuit may still function as the current has other paths. If you wanted to pass through every component in a parallel circuit you would have to travel down every separate branch. What is a Parallel Circuit?Ī parallel circuit is a type of electrical circuit that has a number of different paths for current to flow through. Let’s start by taking a look at what a parallel circuit actually is. We will start by having a look at what a parallel circuit is, we will take a look at what happens to the current in a parallel circuit, some advantages, and disadvantages, and finally some frequently asked questions about parallel circuits. In this article, we will be taking a look at parallel circuits. If you are new to the world of electrical circuitry this can be confusing. Electrical circuits can either be wired in series or parallel.
