Calculating Current Through Resistors in Loop Circuit

AI Thread Summary
To calculate the current through each resistor in the described loop circuit, start by combining the two parallel resistors into an equivalent resistance. This simplifies the circuit, allowing for easier application of Kirchhoff's rules. Once the equivalent resistance is found, use Kirchhoff's current law to determine the current through each branch. The voltage across the parallel resistors remains constant, so apply Ohm's law to find the individual currents. Understanding the resistances of each component is crucial for accurate calculations.

Homework Statement


Find the current through each resistor using the rules for series and parallel resistors and kirchhoff's rules

there is a loop circut with three resistors in parallel, two on top and one on bottom, then one more in series outside of it. It's all attached to a 15 volt cell




The Attempt at a Solution


I can't figure out how to find the different currents. Using the rules for series I can find a current through the whole thing, but not how much is running through each resistor. Help?

What are the resistances of each resistor? Also, your word schematic of the circuit is unclear. If you combine all parallel resistors into equivalent single resistors so that you have a bunch of series resistors, you know by kirchhoffs current law that the current flowing through each of these equivalent resistances is the same. Use the voltage law to find the current through each parallel resistor.
 

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...
