Circuit: current value in generator

AI Thread Summary
The discussion focuses on calculating the magnitude of current in a circuit with an AC voltage source of 158 rms volts, a resistance of 106 ohms, an inductive reactance of 205 ohms, and a capacitive reactance of 110 ohms. The user has identified the need to consider the phase difference between voltage and current due to the reactive components. They have calculated the impedance (Z) and the rms current (Irms) but are uncertain about the phase angle's impact on the maximum current value. The minimum impedance is noted to be equal to the resistance when the load is purely resistive. The conversation highlights the complexities of AC circuit analysis involving reactance and phase relationships.

Homework Statement


AC voltage source rms voltage of 158. Circuit has Resistance 106 X(L) is 205 and X(C) is 110
At the instant the voltage across the generator is at its maximum value, what is the magnitude of the current in teh circuit?

Homework Equations


V=IR, Vmax=ImaxZ
I found Z, Irms


The Attempt at a Solution


voltage across generator is not in phase with the current so it will be less than the max value but I don't know by what factor it will be less

The load can be inductive or capacitive to make phase angle = 0. So the minimum |Z| = R.
 

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...
