Questions about charge flow and electricity

Click For Summary
SUMMARY

The discussion revolves around a GCSE physics homework assignment focused on charge flow and electricity. Key topics include the direction of current in metals, the relationship between chemical compounds and electricity, and the production of hydrogen per coulomb of charge. Participants suggest researching concepts such as voltage, potential, and ions to better understand the subject matter. The user is directed to Wikipedia as a potential resource for further information.

PREREQUISITES
  • Basic understanding of electric current and its direction in conductors.
  • Familiarity with chemical compounds and their behavior in solutions.
  • Knowledge of voltage and electric potential.
  • Understanding of coulombs and their role in electric charge measurement.
NEXT STEPS
  • Research the concept of electric current and its direction in metals.
  • Learn about the relationship between chemical reactions and electricity, particularly in electrolytes.
  • Investigate the concept of voltage and how it affects current flow.
  • Study the production of gases in electrolysis and the calculations involving coulombs.
USEFUL FOR

Students studying GCSE physics, particularly those seeking to understand basic concepts of electricity and charge flow. This discussion is beneficial for anyone needing to complete assignments related to electric current and chemical reactions.

I've just started GCSE physics. I'm pretty happy with everything on the course, but my physics teacher has given me a crazy homework which consists of simple questions about things that we haven't done in lessons. he says that we may need to research a bit, but I can't find anything with google or with bbc bitesize

The questions are ones like this:

  • The direction of the current in a metal is from the side at higher ....., to the side at lower ... This is called the .... current.
  • When some chemical compounds are... or dissolved in ... they ... electricity.

On another page they're harder than just copy and complete. For example:

  • How much hydrogen is produced per coulomb of charge flowing around the circuit? [edit] (they give an example experiment)

I really have no idea about most of this and we haven't covered it in lessons. Could anyone link me to a good informative site where this subject is covered?

Thanks
