  2. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    Lithium-ion rechargeable batteries (particularly laptop batteries) are often connected in parallel to increase the ampere-hour rating. Some solar electric systems have batteries in parallel to increase the storage capacity; a close approximation of total amp-hours is the sum of all amp-hours of in-parallel batteries.

    The transformer has three windings, one for ordinary mains power, the second for rectified battery power, and the third for output AC power to the load. This once was the dominant type of UPS and is limited to around the 150 kVA range. These units are still mainly used in some industrial settings (oil and gas, petrochemical, chemical, utility ...

    en.wikipedia.org/wiki/Battery_pack

    A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery cells and a voltage converter circuitry.

  7. Bridge circuit - Wikipedia

    en.wikipedia.org/wiki/Bridge_circuit

    In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.

  9. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.
