Homework Help Overview

The discussion revolves around understanding Ohm's Law, specifically the proportional relationships between current, voltage, and resistance in electrical circuits. Participants are exploring the definitions and implications of these proportional relationships.

Discussion Character

  • Conceptual clarification, Exploratory

Approaches and Questions Raised

  • The original poster seeks to understand the meaning of "proportional" in the context of Ohm's Law, prompting others to clarify the definitions of direct and indirect proportions as they relate to voltage, current, and resistance.

Discussion Status

Some participants have provided explanations regarding the nature of direct and indirect proportions, contributing to the original poster's understanding. There appears to be a productive exchange of ideas, though no consensus has been reached on all aspects of the topic.

Contextual Notes

The original poster acknowledges that their question may be basic, indicating a potential constraint in their prior understanding of the topic.

Ohm's law states that, in an electrical circuit, the current passing through a conductor between two points is directly proportional to the potential difference (i.e. voltage drop or voltage) across the two points, and inversely proportional to the resistance between them. The mathematical equation that describes this relationship is:

I = V/R
I realize this may be a basic question in electronics however I am looking at it in a new perspective, that of proportions.

Can someone please aide me in comprehending what is defined as (proportional) in this Law.
thanks

The law was formulated as V across two points is directly proportional to the current I. The constant of proportionality was called the resistance R.
 
"Direct proportion" means that as one variable increases, the other increases (more voltage = more current).

"Indirect proportion" means that as one variable increases, the other decreases (more resistance = less current).
 
Thanks Noein your anwser explains what I wanted to know
