SUMMARY

The formula I = -e/T represents the relationship between electric current and the charge of an electron. In this context, electric current (I) is defined as the rate of charge (Q) passing a specific point over time (t), leading to the equation I = Q/t. Here, -e denotes the charge of a single electron, indicating that the current reflects the flow of electrons. This formula is fundamental in understanding basic electrical concepts.

PREREQUISITES
  • Understanding of electric current and charge
  • Familiarity with the symbol representation of charge (Q) and time (t)
  • Basic knowledge of electron charge (-e)
  • Concept of rate in physics
NEXT STEPS
  • Research the principles of electric current and its measurement
  • Study the relationship between charge, current, and time in electrical circuits
  • Explore the significance of electron charge in various physical phenomena
  • Learn about the applications of current in electrical engineering
USEFUL FOR

Students of physics, electrical engineers, and anyone interested in the fundamentals of electric current and charge flow.

Yeah, where does it comes from?

You will have to be more specific and provide context.
 
I'm going to assume your talking about electric current?

In that case, electric current is defined to be the rate of charge passing a particular point.

Charge is given the symbol Q, time t. So if the rate is constant, the current I = Q/t.

In terms of your equation, -e is the charge of one electron, so your current would represent the rate at which a single electron (or something with that amount of charge) passes a particular point.
