Capacitors, Inductors ( finding current and resistance)

AI Thread Summary
The discussion focuses on solving circuit problems involving capacitors and inductors, specifically calculating reactance using the formulas Xl=2*pi*f*l and Xc=1/2*pi*f*c. The user successfully calculated the inductive and capacitive reactance, then combined resistances in parallel to find current using Ohm's law, resulting in I=19. However, confusion arises regarding the circuit configuration in question 6, which is described as ambiguous, particularly with the number of capacitors and values provided. The total reactance is noted to be the difference between inductive and capacitive reactance, but the circuit diagram lacks clarity, leading to uncertainty about the correct arrangement. Overall, the conversation highlights the challenges of interpreting circuit diagrams and the importance of understanding reactance in AC circuits.

Xl=2*pi*f*l, Xc=1/2*pi*f*c, variation of ohms law

The Attempt at a Solution



Ok for 5) i found Xl & Xc, then i combined the resistances in parrallel and used ohms law to find I=v/r. My answer was I=19

For 6) I am complete confused by the circuit, it doesn't make sense to me

For 7) parallel resistor?

Question 6 is a bit ambiguous. The total reactance of the circuit is made up of a capacitive part and an inductive part. The result Xl - Xc is usually referred to as 'the reactance' qualified by the word 'capacitive' of 'inductive' depending on which is the larger.

Anyway in this case - I think it just means the reactance of the capacitor - which you've already calculated.

Figure 12-2 makes no sense at all. There are 2 capacitors but 3 values given
If we assume that one is missing from the drawing, it's probably the 10uF and it could be in parallel with the others, or in series.
Only one configuration would give a value that's offered as an answer.
 
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...
