  2. Current ratio: What it is and how to calculate it - AOL

    www.aol.com/finance/current-ratio-calculate...

    Intel (INTC) at year-end 2023 had $43.27 billion in current assets and $28.05 billion in current liabilities, for a high 1.54 current ratio. What is a good current ratio? The ideal current ratio ...

  3. Current density - Wikipedia

    en.wikipedia.org/wiki/Current_density

    e. In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. [1] The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges ...

  4. Current ratio - Wikipedia

    en.wikipedia.org/wiki/Current_ratio

    The current ratio is a liquidity ratio that measures whether a firm has enough resources to meet its short-term obligations. It compares a firm's current assets to its current liabilities, and is expressed as follows:-. The current ratio is an indication of a firm's liquidity. Acceptable current ratios vary from industry to industry. [1]

  5. Signal-to-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Signal-to-noise_ratio

    The plots at the bottom show the signal intensity in the indicated row of the image (red: original signal, blue: with noise). Signal-to-noise ratio ( SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to noise power ...

  6. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    An electric current is a flow of charged particles, [1] [2] [3] such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface.

  7. Buck converter - Wikipedia

    en.wikipedia.org/wiki/Buck_converter

    The input is left side, the output with load is right side. The switch is typically a MOSFET, IGBT, or BJT transistor. A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input ( supply) to its output ( load ). It is a class of switched-mode power supply.

  8. Power supply rejection ratio - Wikipedia

    en.wikipedia.org/wiki/Power_supply_rejection_ratio

    Power supply rejection ratio. In electronic systems, power supply rejection ratio ( PSRR ), also supply-voltage rejection ratio [1] ( kSVR; SVR ), is a term widely used to describe the capability of an electronic circuit to suppress any power supply variations to its output signal. In the specifications of operational amplifiers, the PSRR is ...

  9. Current transformer - Wikipedia

    en.wikipedia.org/wiki/Current_transformer

    A current transformer ( CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers. Instrument transformers scale the large ...
