AI Thread Summary
A capacitor with a capacitance of 2.56 x 10^-8 F charges to a potential difference of 460 V, resulting in a charge of 1.1776 x 10^-5 C. The number of electrons transferred during this process is calculated using the formula q/e, where e is the elementary charge (1.6 x 10^-19 C). This calculation yields a total of approximately 7.36 x 10^13 electrons. The discussion highlights the importance of knowing the value of the elementary charge when solving capacitor problems. Understanding these concepts is crucial for accurately determining electron transfer in capacitors.

Homework Statement


A capacitor has a capacitance of 2.56 10-8 F. In the charging process, electrons are removed from one plate and placed on the other plate. When the potential difference between the plates is 460 V, how many electrons have been transferred?


Homework Equations


q=CV
Number of Electrons=q/e


The Attempt at a Solution


q=2.56*10^-6*460=1.1776*10^-5

What is e? I assume this is a constant, but I don't have my book on me to find what it is exactly.

Nevermind, e=1.6*10^-19, so the final answer is 7.36*10^13. Sorry for the premature post!

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 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
