AI Thread Summary
To calculate the voltage across capacitors in series, the formula V = Q/C is used, where V is voltage, Q is charge, and C is capacitance. For two capacitors with charges of 5E-6 C and 15E-6 C connected in series with a source voltage of 15V, the total voltage across both capacitors equals the source voltage. The charge on both capacitors remains the same in series, and the individual voltages can be calculated by determining the equivalent capacitance. The voltage across the first capacitor can be found by applying the formula with its specific capacitance. Understanding these principles is essential for analyzing circuits with capacitors in series.

What is the formula for finding the voltage across a capacitor?
 
Physics news on Phys.org
V=\frac{Q}{C}

where V is voltage, Q is the charge, and C is the capacitance.
 
Umm, if I have two in capacitors (5E-6 C and 15E-6 C) in series, and the source voltage is 15V, what would the voltage across the first one be?

I know in parallel it would be 15, but how would you do it if they were in series?
 
in series...the charge on both capacitors is the same n the sum of voltages across the 2=source voltage...now work it out
 

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...
