AI Thread Summary
Finding current in milliamperes (mA) involves converting the calculated current from amperes (A) to milliamperes. Given a voltage of 2.5V and a resistance of 1.6kΩ, the calculation yields a current of 0.0015625 A. To convert this to mA, multiply by 1000, resulting in 1.5625 mA. The discussion emphasizes the importance of unit conversion in electrical calculations. Understanding this process is crucial for accurately reporting current values in the correct units.

Homework Statement



When a question asks you to find current (in mA) what does it mean?

V = 2.5V
R = 1.6kΩ

Homework Equations





The Attempt at a Solution



What I did was

2.5V = I(1600 Ω)
I = 0.0015625 A

Is that correct?

The calculation is correct, but it is not in the requested units.
 


How do i get the correct units?
 


Convert Ampere to milliAmpere.

It is just like converting metre to millimetre or kilometre to metre.
 

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'

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...
