  2. RKM code - Wikipedia

    en.wikipedia.org/wiki/RKM_code

    For example, 8K2 indicates a resistor value of 8.2 kΩ. Additional zeros imply tighter tolerance, for example 15M0. When the value can be expressed without the need for a prefix, an "R" or "F" is used instead of the decimal separator. For example, 1R2 indicates 1.2 Ω, and 18R indicates 18 Ω.

  3. Parallel (operator) - Wikipedia

    en.wikipedia.org/wiki/Parallel_(operator)

    Graphical interpretation of the parallel operator with =.. The parallel operator ‖ (pronounced "parallel", [1] following the parallel lines notation from geometry; [2] [3] also known as reduced sum, parallel sum or parallel addition) is a binary operation which is used as a shorthand in electrical engineering, [4] [5] [6] [nb 1] but is also used in kinetics, fluid mechanics and financial ...

  4. Tolerance analysis - Wikipedia

    en.wikipedia.org/wiki/Tolerance_analysis

    The immediate value to this method is that the output is smooth, but it fails to account for geometric misalignment allowed for by the tolerances; if a size dimension is placed between two parallel surfaces, it is assumed the surfaces will remain parallel, even though the tolerance does not require this.

  5. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    The two preceding statements are equivalent, except for exchanging the role of voltage and current. A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit.

  6. RC time constant - Wikipedia

    en.wikipedia.org/wiki/RC_time_constant

    It is the time required to charge the capacitor, through the resistor, from an initial charge voltage of zero to approximately 63.2% of the value of an applied DC voltage, or to discharge the capacitor through the same resistor to approximately 36.8% of its initial charge voltage.

  7. Load regulation - Wikipedia

    en.wikipedia.org/wiki/Load_regulation

    The values of the resistors are selected such that R 1 gives the highest load resistance, R 1 ||R 2 gives the nominal load resistance and either R 1 ||R 2 ||R 3 or R 2 ||R 3 gives the lowest load resistance. A voltmeter is then connected in parallel to the resistors and the measured values of voltage for each load state can be used to calculate ...

  8. Norton's theorem - Wikipedia

    en.wikipedia.org/wiki/Norton's_theorem

    At a pair of terminals of the network, it can be replaced by a current source and a single resistor in parallel. For alternating current (AC) systems the theorem can be applied to reactive impedances as well as resistances. The Norton equivalent circuit is used to represent any network of linear sources and impedances at a given frequency.

  9. Engineering tolerance - Wikipedia

    en.wikipedia.org/wiki/Engineering_tolerance

    This is just one example for linear tolerances for a 100 mm value. This is just one of the 8 defined ranges (30–120 mm). Engineering tolerance is the permissible limit or limits of variation in: a physical dimension; a measured value or physical property of a material, manufactured object, system, or service;
