Finding current and equivalent resistance

AI Thread Summary
To find the current through points C, D, and G in the circuit with a 48.0 V battery and five resistors, the equivalent resistance was calculated as 193 Ω. The next step involves using Kirchhoff's Current and Voltage Laws to determine the voltage drop across R1, which will aid in calculating the currents through the other resistors. The currents at points C and G will be the sum of the currents at R4 and R5. By applying the voltage drop to the remaining resistors, the individual currents can be determined. Understanding these principles is crucial for solving the circuit problem effectively.

Homework Statement


The circuit consists of a battery (V0 = 48.0 V) and five resistors (R1 = 111 Ω, R2 = 182 Ω, R3 = 663 Ω, R4 = 334 Ω, and R5 = 465 Ω). Find the current passing through C, D, and G.

The Attempt at a Solution


I tried to find the equivalent resistance (Req = 193 Ω). The problem had a hint that said after that, I need to work backwards to find the currents. I understand that C and G will be the sum of the currents at R4 and R5, but I don't know how to find the currents at R4 and R5.

If you know the equivalent resistance of the circuit then you can calculate the
voltage drop across R1. Then you should easily be able to calculate the currents
thru the remaining resistors.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
