SUMMARY

The discussion revolves around a homework problem related to electrical circuits, specifically involving the time constant formula T = RC, where R represents resistance and C represents capacitance. The user is attempting to calculate the time constant and subsequently divide the times by this value to solve the problem. A reference link to HyperPhysics is provided for further clarification on capacitor charging. The user seeks assistance in confirming the formula and understanding the next steps in their calculations.

PREREQUISITES
  • Understanding of electrical circuits and components, specifically resistors and capacitors.
  • Familiarity with the time constant concept in RC circuits.
  • Basic algebra skills for manipulating formulas and calculations.
  • Access to online physics resources, such as HyperPhysics, for additional context.
NEXT STEPS
  • Review the concept of the time constant in RC circuits.
  • Practice calculations involving T = RC with different values of R and C.
  • Explore capacitor charging and discharging equations in detail.
  • Utilize online physics simulation tools to visualize RC circuit behavior.
USEFUL FOR

Students studying electrical engineering or physics, educators looking for teaching resources, and anyone needing clarification on RC circuit calculations.

I'm trying to figure out the answer to a homework problem, but I just don't know the formula. :|
I was going to explain it, but I figure a pic is easier.

Now, I think you start with T = RC? With that, I get 1 sec. Then I divide each of the times by that? Rrrrrr! Can someone tell me what formula to use or give me a clue, at least? :(
