How Do You Calculate Total Resistance, Current, and Power in a Complex Circuit?

AI Thread Summary
To calculate total resistance, current, and power in a complex circuit, start by determining the equivalent resistance using both series and parallel formulas. The user initially calculated the equivalent resistance of a parallel circuit as 0.4 ohms but is uncertain about the next steps. It's essential to apply Ohm's Law by identifying the voltage and current in the circuit. Further clarification is needed on the combination of resistors, as the current calculation appears incorrect. Accurate calculations will lead to determining voltage, current, resistance, and power for each resistor and the overall circuit.

Homework Statement



http://imgur.com/h5VXibe

Have to solve V, I, R and Power for all resistors and the circuit total. Known data is shown in table. The rest needs to be solved for

Homework Equations



Ohm's Law and Series Equation: 1/Er=1/R1+1/R2... and Tr=R1+R2...

The Attempt at a Solution



Added up parallel circuit and found Er to be .4 ohms. Not sure where to go next.

Begin by finding the equivalent resistance for the whole circuit by applying Ohms law to the circuit.
 
I'm not sure how to approach that.

You know Ohms law right? What's the voltage applied to the circuit and what's the current moving through it?

Please show your work. The combination of R2, R3, R4 is not 0.4 Ohms...
 

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...
