What is the function of extension boards?
An extension board or power strip extension board is made up of multiple sockets, each connected to an elastic power cable enclosed in a shockproof plastic shell. The power strip draws electricity from wall sockets, and distributes it between devices that are connected to these sockets. Extension boards may differ in style with some featuring features such as individual switches or LED indicators that show the current socket being utilized. The main benefit that extension boards have is that they distribute power evenly between the devices connected. This makes it possible for all devices to work flawlessly. This can be achieved by connecting each socket in a ‘parallel’ fashion to one another.
The flow of current is between two points with different potentials. For the current to move through a circuit it has to be connected to the power source which creates the potential difference. That potential gap is called voltage. The flow of electricity in the circuit is controlled by Ohm’s law, which defines voltage as a function of the circuit’s resistance as well as the flow of current that flows through it. Mathematically, it can be represented by the formula: V = I, in which V represents the voltage flowing through the circuit and I is the flow of the current, and R is the resistance that is provided by the circuit to allow the flow of the current. All devices that are connected to the circuit draw the current and thus create resistance to prevent it from moving into the circuit. This is why they are referred to as an. In the context of how resistors in the circuit, circuits could be classified as either parallel or series.

Parallel circuits are where all resistors are connected to the same power source, but along specific pathways. Since each appliance has its own circuit, every appliance is supplied with the same voltage. The current they draw is contingent on their specific resistances, which makes the total drawn current a equal sum of the different currents that each appliance draws. The flow of current through one circuit of an asynchronous circuit is not dependent on the other. This makes parallel circuits extremely useful for extension boards.
Protection against surges
While the fundamental principle behind extension boards is fairly simple, the boards are far more than just a simple arrangement of circuits in parallel. They have to be designed keeping consideration of the energy requirements of the devices that are linked to them. Because parallel circuits can draw large currents, it’s essential to include surge protection to avoid the damage caused by electricity or even fires or short circuits.
Cut-offs of the fuse
Fuses are safety devices placed in between power supplies and devices in circuits that are able to draw huge currents. They are made from an extremely poor conductor like an alloy consisting of lead and tin. This allows them to melt when current is greater than their maximum. When they melt the circuit, it breaks and disrupts the flow of current to appliances while also protecting them from harm. By utilizing miniature circuit breakers (MCBs) in modern electrical mains, a further layer of protection protects against electrical accidents.
Extension boards that are able to support several devices typically have three-pin plugs that aid with the grounding. Grounding or earthing is the safe redirection of current that is excessive to the surface which is in a low voltage. It is a safety action for devices connected to the power strip. It is generally recommended to not connect multiple drawing devices with a heavy weight to one extension cable. But, if it’s essential to do this it is best to make use of extension cords that are capable of handling such a large current flux. Extension cords also have LED indicators and switches for every socket, allowing users to have more control. The flow of electricity to one socket can be turned off or on with the appropriate switch, independent of the other sockets.
