  2. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. [1] In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each ...

  3. RC circuit - Wikipedia

    en.wikipedia.org/wiki/RC_circuit

    The current in the circuit is the same everywhere since the circuit is in series: () ... These equations show that a series RC circuit has a time constant, ...

  4. Current divider - Wikipedia

    en.wikipedia.org/wiki/Current_divider

    In electronics, a current divider is a simple linear circuit that produces an output current (I X) that is a fraction of its input current (I T). Current division refers to the splitting of current between the branches of the divider. The currents in the various branches of such a circuit will always divide in such a way as to minimize the ...

  5. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    A flow of positive charges gives the same electric current, and has the same effect in a circuit, as an equal flow of negative charges in the opposite direction. Since current can be the flow of either positive or negative charges, or both, a convention is needed for the direction of current that is independent of the type of charge carriers ...

  6. Load line (electronics) - Wikipedia

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

    Since the same current flows through each of the three elements in series, and the voltage produced by the voltage source and resistor is the voltage across the terminals of the diode, the operating point of the circuit will be at the intersection of the curve with the load line.

  7. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    Series RL, parallel C circuit with resistance in series with the inductor is the standard model for a self-resonant inductor. A series resistor with the inductor in a parallel LC circuit as shown in Figure 4 is a topology commonly encountered where there is a need to take into account the resistance of the coil winding and its self-capacitance.

  8. Kirchhoff's circuit laws - Wikipedia

    en.wikipedia.org/wiki/Kirchhoff's_circuit_laws

    The current entering any junction is equal to the current leaving that junction. i 2 + i 3 = i 1 + i 4. This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or equivalently:

  9. Talk:Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Talk:Series_and_parallel...

    "Simply put, in a parallel circuit current increases but the voltage stays the same, and in a series circuit current stays the same but the voltage increases". In a series circuit the voltage actually decreases after each resistor, also known as voltage drop. Let's say we have a series circuit with 12v and 2 resistors.
