A linear regulator is a system used to maintain a steady voltage. The resistance of the regulator varies in accordance with the load resulting in a constant voltage output Because a linear voltage regulator is very common & integral to a number of other elements, regulators ICs are very popular.

An adapter is a physical device that allows one hardware or electronic interface to be adapted (accommodated without loss of function) to another hardware or electronic interface. In a computer, an adapter is often built into a card that can be inserted into a slot on the computer's motherboard.
An adapter 12V 2A is a physical device that allows one hardware or electronic interface to be adapted (accommodated without loss of function) to another hardware or electronic interface. In a computer, an adapter is often built into a card that can be inserted into a slot on the computer's motherboard.
An extension cord, power extender, drop cord or extension lead is a contraption (box) with sockets mounted on it, providing for extension of power sockets at the other end, typical 4,5 and 6-sockets. Today's extension cords/ strips have additional voltage/ current 'spike arresting' capabilities safeguarding the load connected to these sockets.
9V BATTERY CLIPac GENERAL DESCRIPTION. 9-volt battery in its most common form was introduced for the early transistor radios. It has a rectangular prism shape with rounded edges and a polarized snap connector at the top. This type is commonly used in walkie talkies, clocks and smoke detectors.
A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it.
The charging protocol (how much voltage or current for how long, and what to do when charging is complete, for instance) depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging (i.e., continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle, and some battery types absolutely require, or may use a timer, to cut off charging current at some fixed time, approximately when charging is complete. Other battery types cannot withstand over-charging, being damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.
As a thumb-rule, 1 KVA UPS can support 3-4 PCs/Laptops (with TFT Monitors), simple routers/switches and a simple EPABX. Online UPS typically come in 1KVA, 2KVA,3,5 and 10 KVA and above. While planning for your UPS capacity, it's better to plan for somewhat higher capacity for future capacity.
