Discussion Overview

The discussion revolves around the relationship between electromotive force (EMF) and current, specifically whether they can be considered equal under certain conditions. The scope includes conceptual understanding and theoretical implications in electrical circuits.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions if EMF can equal current when the circuit has no consumer, suggesting a potential condition where the equation might hold.
  • Another participant asserts that EMF and current are fundamentally different quantities and cannot be equal, using an analogy to illustrate this point.
  • Further replies reinforce the idea that EMF and current cannot be equal, reiterating the analogy of comparing unrelated items.
  • A participant expresses gratitude for the clarification provided, indicating that the responses helped resolve their confusion.

Areas of Agreement / Disagreement

Participants generally disagree on the possibility of EMF being equal to current, with one participant proposing a specific condition while others firmly reject the idea.

As the title states, can EMF = I = const ?

Where did you come across that equation? emf and current are two different types of quantities. They cannot be equal. It is like saying 2 oranges = 3 elephants
 
Thats what i thought, but what if the circuit has no consumer, can the equatiuon work then ?
 
Nothing matters. The two can never be equal. It still says 2 oranges = 3 elephants.

Thank you for your answer. I think this cleared my head.
