  2. Electrical isolation test - Wikipedia

    en.wikipedia.org/wiki/Electrical_isolation_test

    In electrical engineering, an electrical isolation test is a direct current (DC) or alternating current (AC) resistance test that is performed on sub-systems of an electronic system to verify that a specified level of isolation resistance is met.

  3. Current clamp - Wikipedia

    en.wikipedia.org/wiki/Current_clamp

    The clamp measures the current and other circuitry the voltage; the true power is the product of the instantaneous voltage and current integrated over a cycle. Comprehensive meters designed to measure many parameters of electrical energy ( power factor , distortion , instantaneous power as a function of time, phase relationships, etc.), use ...

  4. Iddq testing - Wikipedia

    en.wikipedia.org/wiki/Iddq_testing

    Test application time is fast since the vector sets are small. It catches some defects that other tests, particularly stuck-at logic tests, do not. Drawback: Compared to scan chain testing , Iddq testing is time consuming, and thus more expensive, as is achieved by current measurements that take much more time than reading digital pins in mass ...

  5. Load line (electronics) - Wikipedia

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

    Once a DC operating point is defined by the DC load line, an AC load line can be drawn through the Q point. The AC load line is a straight line with a slope equal to the AC impedance facing the nonlinear device, which is in general different from the DC resistance. The ratio of AC voltage to current in the device is defined by this line.

  6. Continuity test - Wikipedia

    en.wikipedia.org/wiki/Continuity_test

    In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path.

  7. Test probe - Wikipedia

    en.wikipedia.org/wiki/Test_probe

    The classic current probe is a low valued resistor (a "sampling resistor" or "current shunt") inserted in the current's path. The current is determined by measuring the voltage drop across the resistor and using Ohm's law. (Wedlock & Roberge 1969, p. 152.) The sampling resistance needs to be small enough not to affect circuit operation ...

  9. Current limiting - Wikipedia

    en.wikipedia.org/wiki/Current_limiting

    An inrush current limiter is a device or devices combination used to limit inrush current. Passive resistive components such as resistors (with power dissipation drawback), or negative temperature coefficient (NTC) thermistors are simple options while the positive one (PTC) is used to limit max current afterward as the circuit has been operating (with cool-down time drawback on both).
