    The cap on the calculation of basic allowance is Rs. 15,000.00. Further, the basic plus the allowances received by all employees across the board should be considered for calculation of EPF wages, not the gross wages for the calculation of EPF dues.

  4. Electron cyclotron resonance - Wikipedia

    en.wikipedia.org/wiki/Electron_cyclotron_resonance

    The ECR ion source makes use of the electron cyclotron resonance to ionize a plasma. Microwaves are injected into a volume at the frequency corresponding to the electron cyclotron resonance, defined by the magnetic field applied to a region inside the volume. The volume contains a low pressure gas.

    PFD allowance in work systems is the adjustment done to the normal time to obtain the standard time for the purpose of recovering the lost time due to personal needs, fatigue, and unavoidable delays. [1]

  6. ESR meter - Wikipedia

    en.wikipedia.org/wiki/ESR_meter

    Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...
