Discussion Overview

The discussion revolves around the behavior of current in a series resistor circuit, specifically addressing why the current remains the same despite the presence of resistance. Participants explore concepts related to resistance, voltage sources, and the flow of current in electrical circuits.

Discussion Character

  • Conceptual clarification
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants question why the current is the same in a series circuit despite resistance opposing current flow.
  • One participant suggests that conservation of energy principles may provide insight into the behavior of current in these circuits.
  • Another participant mentions that adding or removing a load affects the current value, implying that the current is not constant in all scenarios.
  • A participant explains that a voltage source adjusts the current based on the total resistance in the circuit, referencing Ohm's law.
  • There is a perspective that current can be viewed as a quantity of electrons flowing through resistances, where the flow is slowed down by resistance, leading to a voltage drop.

Areas of Agreement / Disagreement

Participants express differing views on the constancy of current in series circuits, with some emphasizing the role of resistance and others focusing on the influence of voltage sources and circuit configurations. The discussion remains unresolved regarding the underlying reasons for the behavior of current in these contexts.

Contextual Notes

Participants have not fully explored the implications of their statements, and assumptions about circuit behavior, such as the role of voltage sources and the nature of current flow, are not explicitly defined.

resistance is oppsition to the flow of current then why the current is same in series resistive ciruit..??

Any complex circuit can be simplified, this being the case -- what does current see entering a circuit?
 
Remove or add a load and you will see that the current value changes.
 
soft land, if you have a voltage source connected to one resistance, what will happen is that the voltage source will look through it's terminals finds the amount of resistance connected to it and figure out who much current it can give to the circuit by applying ohm's law and then outputs that current. now if you connect two resistances in series the voltage source will again look at it's terminal only this time to find that the resistance have increased thus adjusting the current given to the circuit.

Also another way to look at it is that the current is a given quantity of electrons flowing through the resistance. when the current passes through the resistance or "opposition" it slows down but it must pass -where else would it go- this slow-down is simply the voltage drop across the resistance.
