How many electrons flow through this device?

Click For Summary
SUMMARY

The discussion centers on calculating the number of electrons flowing through an electric device that delivers a current of 2.44 A for 55.0 seconds. The key equations used are Q=It, where Q is the total charge, I is the current, and t is the time, and Q=ne, where n is the number of electrons and e is the charge of an electron (approximately 1.6 x 10-19 coulombs). The user successfully solved the problem by applying these equations to determine the total charge and subsequently the number of electrons.

PREREQUISITES
  • Understanding of electric current and the definition of an ampere
  • Familiarity with the concept of charge and the charge of an electron
  • Basic knowledge of algebra for manipulating equations
  • Ability to perform unit conversions and calculations involving time
NEXT STEPS
  • Study the relationship between current, charge, and time using the equation Q=It
  • Learn about the fundamental properties of electrons, including their charge and mass

Homework Statement



An electric device delivers a current of 2.44 A for 55.0 seconds. How many electrons flow through this device?

Homework Equations





The Attempt at a Solution



I am clueless, i need help
 
Physics news on Phys.org


Whats the definition of an amp?
Whats the charge of an electron
 


An amp is a unit of electric current, and a an electron has a negative charge.
Still clueless
 


I need help with this question. It don't make sense, can you help me with answering the problem
 


Oh never mind, I just figured it out. I did not know the equation Q=It or Q=ne
