How Do Electrical Equations Help Calculate Charge and Electron Flow in Circuits?

AI Thread Summary
The discussion focuses on understanding key electrical equations and variables used to calculate charge and electron flow in circuits. The variables include the charge of an electron (e), the total charge (Q), and the formula for current (I), which relates charge to time. A current of 0.82 A flowing for 10 minutes results in a charge of 492 Coulombs, but a discrepancy with the book's answer suggests a calculation error. For calculating the number of electrons, knowing that one Coulomb equals approximately 6.24 x 10^18 electrons is essential. The conversation emphasizes the importance of correctly applying these equations to solve electrical problems.

Can you please explain me in lamens terms what are these variables names and what they give:
-
1c=6.24 * 10^18
e=1.60 * 10^-19
Q=Ne
Fe=KQ1Q2/d^2
I=Q/T
1A = 1C/1s
-
And How would i do this question with the stuff i have written above this line?
-
A current of 0.82 A flows through an electric lamp for 10 min. In that time how much charge passes a given spot in the filament expressed in
(a)Coulombs
(b)Electrons
-
For (a) i think I need to use 1A = 1C/1s
So C=A*S
-C=0.82 A (600s)
-C=492
But in the back of my book its -492 explain what i did wrong
-
For (b) I think i don't know what to use I'm

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
