  2. Failure of electronic components - Wikipedia

    en.wikipedia.org/wiki/Failure_of_electronic...

    The damaged transistor shows a low-ohmic junction between gate and drain terminals. A parametric failure only shifts the device parameters and may manifest in stress testing; sometimes, the degree of damage can lower over time. Latent ESD failure modes occur in a delayed fashion and include: Insulator damage by weakening of the insulator ...

  3. Battery indicator - Wikipedia

    en.wikipedia.org/wiki/Battery_indicator

    In battery types where EMF remains approximately constant during discharge, but resistance increases, voltage across battery terminals is not a good indicator of capacity. A meter such as an equivalent series resistance meter ( ESR meter ) normally used for measuring the ESR of electrolytic capacitors can be used to evaluate internal resistance ...

  4. Battery terminal - Wikipedia

    en.wikipedia.org/wiki/Battery_terminal

    General Motors, and other automobile manufacturers, have also begun using side-post battery terminals, which consist of two recessed female 3/8" threads (SAE 3/8-16) into which bolts or various battery terminal adapters are to be attached. These side posts are of the same size and do not prevent incorrect polarity connections.

  5. Negative resistance - Wikipedia

    en.wikipedia.org/wiki/Negative_resistance

    In a power source, like a battery or electric generator, positive current flows out of the positive voltage terminal, [26] opposite to the direction of current in a resistor, so from the passive sign convention and have opposite signs, representing points lying in the 2nd or 4th quadrant of the I–V plane (diagram right).

  6. Contact resistance - Wikipedia

    en.wikipedia.org/wiki/Contact_resistance

    Bad contacts are the cause of failure or poor performance in a wide variety of electrical devices. For example, corroded jumper cable clamps can frustrate attempts to start a vehicle that has a low battery. Dirty or corroded contacts on a fuse or its holder can give the false impression that the fuse is blown.

  7. Terminal (electronics) - Wikipedia

    en.wikipedia.org/wiki/Terminal_(electronics)

    Terminal symbol A terminal strip, to which wires can be soldered. A terminal is the point at which a conductor from a component, device or network comes to an end. [1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.

  9. Cathode - Wikipedia

    en.wikipedia.org/wiki/Cathode

    A battery or galvanic cell in use has a cathode that is the positive terminal since that is where conventional current flows out of the device. This outward current is carried internally by positive ions moving from the electrolyte to the positive cathode (chemical energy is responsible for this "uphill" motion).
