How Do You Calculate the Input Power of a Series RLC Circuit?

AI Thread Summary
To calculate the input power of a series RLC circuit, one must first determine the phase angle and power factor. The circuit components include a resistor (R = 250 Ω), inductor (L = 0.300 H), and capacitor (C = 3.00 µF), with a voltage source of ΔVmax = 240 V at 70.0 Hz. The power input can be calculated using the formula P = I^2R, where only the resistor dissipates power. Understanding the relationship between voltage, current, and the circuit's impedance is crucial for accurate calculations.

The Attempt at a Solution



I've searched through my book but I cannot find how to calculate the input power of the circuit.
I've tried to use P=IV to find the input power, but I still cannot find the correct answer.:cry:

Only one of those elements dissipates power. Which element is that?

What is a formula that gives the power that element dissipates?

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...
