    en.wikipedia.org/wiki/Cathode_bias

    Any signal frequency effect of the cathode resistor may be minimized by providing a suitable bypass capacitor in parallel with the resistor. In general, the capacitor value is selected such that the time constant of the capacitor and bias resistor is an order of magnitude greater than the period of the lowest frequency to be amplified.

    Common accuracy specifications of such devices are ±0.1%, ±0.25% or ±0.5%. The Thomas-type double manganin walled shunt and MI type (improved Thomas-type design) were used by NIST and other standards laboratories as the legal reference of an ohm until superseded in 1990 by the quantum Hall effect .

    The moving-iron meter was invented by Austrian engineer Friedrich Drexler in 1884. [5] This type of meter responds to both direct and alternating currents (as opposed to the moving-coil ammeter, which works on direct current only). The iron element consists of a moving vane attached to a pointer, and a fixed vane, surrounded by a coil.
