• Conceptualization

    • Circuits with resistors associated in series characteristics

      • A component depends on the other so the circuit can work

      • The resistors are covered by the same amount of electric value

      • The voltage applied to the circuit is divided on the associated resistors (depends on the value of resistance)

      • The power dissipated in the equivalent resistor is equal to the sum of the power dissipated by each resistor of the association

      • The total circuit resistance (equivalent resistor) is obtained from the sum of the resistances of the circuit.

    • Circuits with resistors associated in parallel characteristics

      • The electrical current supplied by the source is divided between the circuit resistors and depends on the value of resistance

      • The components are electrically independent from each other

      • The voltage is the same for all resistors, as they are connected at the ends of the source

      • The total resistance of the circuit (equivalent resistance) is lower than the smallest resistance associated

      • The power dissipated in the equivalent resistor is equal to the sum of the power dissipated by each resistor of the association

    • Circuit with mixed associated resistors

      In a circuit with mixed associated resistors appear both in parallel and in series. According to Oliveira et al. (2013), to set the value of the equivalent resistance circuits mixed must associate each set of resistors, whether series or parallel, simplifying connection of parts, to get a single resistor to replace the entire circuit.

    • Curiosities

      Did you know that the more electrical appliances are connected in a certain section of the largest electrical circuit the intensity of electrical current required to operate these devices?

      What happens in an electric circuit when many electrical devices are connected at the same time?
