  2. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    If the cells are connected in series, the voltage of the battery will be the sum of the cell voltages. For example, a 12 volt car battery contains six 2-volt cells connected in series. Some vehicles, such as trucks, have two 12 volt batteries in series to feed the 24-volt system.

  3. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

  4. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    On a circuit diagram, the symbols for components are labelled with a descriptor or reference designator matching that on the list of parts. For example, C1 is the first capacitor, L1 is the first inductor, Q1 is the first transistor, and R1 is the first resistor. Often the value or type designation of the component is given on the diagram ...

  5. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  6. Battery nomenclature - Wikipedia

    en.wikipedia.org/wiki/Battery_nomenclature

    Lithium-ion batteries have a different rule for naming, which applies both to batteries of multiple cells and single cell. They will be designated as: [13] N 1 A 1 A 2 A 3 N 2 /N 3 /N 4-N 5. where N 1 denotes number of series connected cells and N 5 denotes number of parallel connected cells (only when the number is greater than 1); these ...

  7. Electrical wiring - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring

    Electrical symbols for wiring [vague] Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation.

  8. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    For example, a battery for an electronic artillery fuze might be activated by the impact of firing a gun. The acceleration breaks a capsule of electrolyte that activates the battery and powers the fuze's circuits. Reserve batteries are usually designed for a short service life (seconds or minutes) after long storage (years).

  9. Daisy chain (electrical engineering) - Wikipedia

    en.wikipedia.org/wiki/Daisy_chain_(electrical...

    For example, chaining multiple components that each have a UART port to each other. The components must also behave cooperatively. e.g., only one seizes the communications bus at a time. SCSI is an example of a digital system that is electrically a bus, in the case of external devices, is physically wired as a daisy chain. Since the network is ...
