2. Battery isolator - Wikipedia

   en.wikipedia.org/wiki/Battery_isolator

   A battery isolator is an electrical device that divides direct current (DC) into multiple branches and only allows current in one direction in each branch. The primary benefit of such an arrangement is the ability to simultaneously charge more than one battery from a single power source (e.g., an alternator) without connecting the battery terminals together in parallel.

3. Ground loop (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_loop_(electricity)

   Battery-powering one or more of the circuits can avoid a ground loop, because the entire device may be disconnected from mains power. A hazardous technique sometimes used by amateurs is to break the third wire ground conductor P in one of the component's power cords, by removing the ground pin on the plug, or using a cheater plug .

4. Galvanic isolation - Wikipedia

   An opto-isolator is a very popular method of isolation in digital circuits. Cross-section of dual in-line package opto-isolators. Relative sizes of LED (red) and sensor (green) are exaggerated. Everlight EL817 phototransistor opto-isolator in DIP-4 package Halo TG110-S050N2RL 10/100BASE-TX Ethernet pulse transformer in SO-16 package, with the ...

5. Duality (electrical circuits) - Wikipedia

   en.wikipedia.org/wiki/Duality_(electrical_circuits)

   The dual expression thus produced is of the same form, and the reason that the dual is always a valid statement can be traced to the duality of electricity and magnetism. Here is a partial list of electrical dualities: voltage – current; parallel – series (circuits) resistance – conductance; voltage division – current division ...

6. Metadyne - Wikipedia

   en.wikipedia.org/wiki/Metadyne

   The equipment was particularly suitable for battery locomotives, as the lack of starting resistances reduced the amount of power wasted when starting and stopping frequently. At slow speeds, conventional control systems would often overheat, but the metadyne-equipped locomotives could pull trains weighing 100 tons for long distances at speeds ...

7. Opto-isolator - Wikipedia

   en.wikipedia.org/wiki/Opto-isolator

   Schematic diagram of an opto-isolator showing source of light (LED) on the left, dielectric barrier in the center, and sensor (phototransistor) on the right [note 1]. An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. [1]

   Separable assembly or sub-assembly (e.g. printed circuit assembly) AT: Attenuator or isolator: BR: Bridge rectifier (four diodes in a package) often changed to "D" for diode BT, BAT: Battery or battery holder: often shortened to "B" C: Capacitor: CB: Circuit breaker: CN: Capacitor network: may be simplified to "C" for capacitor D, CR: Diode ...

9. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   A feedback circuit monitors the output voltage and compares it with a reference voltage. Depending on design and safety requirements, the controller may contain an isolation mechanism (such as an opto-coupler) to isolate it from the DC output. Switching supplies in computers, TVs and VCRs have these opto-couplers to tightly control the output ...
