AI Thread Summary
The discussion revolves around solving a hydrogen discharge electricity numerical problem involving current calculation. The current is determined using the formula Q=I x t, where the charge of electrons is essential for the calculation. Participants suggest looking into the concept of 'Conventional Current flow' to understand the direction of current. There is also a recommendation to post homework questions in a designated help section for more focused assistance. Overall, the thread emphasizes the importance of understanding basic electrical principles to solve the problem effectively.

electricity numericals! help needed!

When a sufficiently high voltage is applied between two electrodes in a gas, the gas ionises. Electrons move towards the positive electrodes,and positive ions move towards the negative electrode.

a) what is the current in a hydrogen discharge if, in each second, 4.4 x 10^15 electrons and 1.5x 10^15 protons move in opposite directions past a cross-section of the tube?
b)what is the direction of the current? :confused:

This sounds like a homework problem.

Tell us what your thoughts are on the problem.
 
a) Start with Q=I x t
You should know the charge on an electron.

b) Look up 'Conventional Current flow'.

c) Post HWK in the HWK help section.
 
thanx for your help.
 
No problem.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
