  2. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    If the cells of a battery are connected in parallel, the battery voltage will be the same as the cell voltage, but the current supplied by each cell will be a fraction of the total current. For example, if a battery comprises four identical cells connected in parallel and delivers a current of 1 ampere , the current supplied by each cell will ...

  3. Two capacitor paradox - Wikipedia

    en.wikipedia.org/wiki/Two_capacitor_paradox

    Two identical capacitors are connected in parallel with an open switch between them. One of the capacitors is charged with a voltage of V i {\displaystyle V_{i}} , the other is uncharged. When the switch is closed, some of the charge Q = C V i {\displaystyle Q=CV_{i}} on the first capacitor flows into the second, reducing the voltage on the ...

  4. Commutation cell - Wikipedia

    en.wikipedia.org/wiki/Commutation_cell

    This applies to classical sources (battery, generator) and capacitors and inductors: At a small time scale, a capacitor is identical to a voltage source and an inductor to a current source. Connecting two capacitors with different voltage levels in parallel corresponds to connecting two voltage sources, one of the forbidden connections in figure 1.

  5. Bridge circuit - Wikipedia

    en.wikipedia.org/wiki/Bridge_circuit

    It is constructed from four resistors, two of known values R 1 and R 3 (see diagram), one whose resistance is to be determined R x, and one which is variable and calibrated R 2. Two opposite vertices are connected to a source of electric current, such as a battery, and a galvanometer is connected across the other two vertices. The variable ...

  6. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2]

  7. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    If the goal is to increase capacity and prolong the runtime of the inverter, batteries can be connected in parallel. This increases the overall ampere hour (Ah) rating of the battery set. If a single battery is discharged though, the other batteries will then discharge through it.

  9. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    This circuit does not have a resistor like the above, but all tuned circuits have some resistance, causing them to function as an RLC circuit. An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that ...
