Why are households wired in a parallel circuit

It is mostly used in battery-operated electrical devices such as a torch. The wiring runs continuously from the positive terminal of the battery, through the bulb and switch to the negative terminal. With this configuration all elements are part of the circuit.

If any of these devices were removed or failed, the current would stop flowing. If the lights in your home were connected this way, you could only have one main switch that would turn on all the bulbs simultaneously, and every time a bulb burned out you would have to change it in order to maintain light throughout the house. In other words, all the input connectors coincide with one another, as do the output terminals. By splitting the main circuit we can connect several devices in parallel so that, even if one of element fails, the current does not stop flowing to the rest of the elements.

Having already seen the basic characteristics of the two configurations, it is easy to imagine that it is not viable to have various electrical devices at home connected in series. By opting for parallel connection, you can have several sockets, something that would not be possible in a series connection. All kinds of elements can be connected to the mains, without the need for them all to be switched on at the same time. In a parallel circuit, if one appliance is turned off or fails, electricity can still flow through the main circuit, energizing the other appliances.

Every time you add an appliance to a parallel circuit, the amperage or rate of electrical flow through the circuit increases. As amperage is increased, heat is generated in the wires. Overheated wiring can cause combustion, leading to a house fire. Fuses and breakers act as switches that automatically open the circuit or turn off the electricity before high amperage causes overheating of the wire.

Disadvantages of using series circuits in domestic wiring The voltage will be split through all electrical devices in a series circuit. The total circuit resistance will increase because the current from the power supply will be less.

In a series connection, the amount of current flowing through the two appliances is same whereas, in case of a parallel connection, the voltage across each appliance is the same. A parallel circuit can consume more power when compared to a series circuit. At the same time, parallel circuits can be more robust. The parallel capacitors holds more charge but work same as one capacitor filtration.

The two resistors have the same current through them. The potential difference across them will be different if they have different resistances. Electrical appliances are connected in a parallel arrangement in a house circuit because: Each appliance gets full voltage as resistance in a parallel arrangement is low.

If one appliance fuses, it does not affect the working of other appliances. We can use one appliance without using other appliances.

What is the voltage measured across a series short? Explanation: A short is just a wire. The potential difference between two points of a wire is zero hence the voltage measured is equal to zero. In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component.

If one bulb burns out in a series circuit, the entire circuit is broken. The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops.

If the circuit is broken at any point, no current will flow. The sum of the voltages across components in series is equal to the voltage of the supply. The voltages across each of the components in series is in the same proportion as their resistances. This means that if two identical components are connected in series, the supply voltage divides equally across them.

Potential difference in a series circuit. The total potential difference supplied by the cell is divided up between the components.
