Balancing is only necessary for packs that contain more than one cell in series. Parallel cells will naturally balance since they are directly connected to each other, but groups of parallel wired cells, wired in series (parallel-series wiring) must be balanced between cell groups.
Laboratory-grade Zener diode secondary solid-state voltage standards used in metrology can be constructed with a drift of about 1 part per million per year. [ 1 ] The value of the " conventional " volt is now maintained by superconductive integrated circuits using the Josephson Effect to get a voltage to an accuracy of 1 parts per billion or ...
A secondary battery; a battery that can have a useful portion of its capacity restored by connection to a supply of electric current. reciprocity (electrical networks) A theorem that states that the current injected into one point in a network will produce a voltage at a second point that is identical to the voltage produced at the first point ...
Volt announced the SEC investigation on November 8, 2010. The company has concurrently performed an internal review of its accounting for revenue and related costs as well as other areas, and is ...
The condition for balance of lines and circuits will be met, in the case of passive circuitry, if the impedances are balanced. The line and circuit remain balanced, and the benefits of common-mode noise rejection continue to apply, whether or not the applied signal is itself balanced (symmetrical), always provided that the generator producing ...
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

The balance board's development was tightly coupled with the development of the Wii Fit game. Nintendo initially contacted manufacturers of normal bathroom scales, but ended up building the board without their help in an effort to keep down costs. In early development models, the balance board was a simple scale with one load cell.
