Here are two examples of RLC-circuits where phasor diagrams work, one serial and one parallel YouTube RLC tutorial. I was thinking the one where it didn't work might be a more complicated circuit, which was first serial then parallel, but I'm not sure.

When I studied Electronics I remember that there was some type of RLC-circuit where phasor diagrams could not be applied in order to find I, U and phi_u_i (φ_u_i). I've been searching the web to find that example. But I can't find it. Can anyone of you help me refresh my memory?

According to the Drake Equation there are probably 10,000 communicable civilizations in the Milky Way at the same level of development as the human civilization on Earth or even more advanced. And if there are 100 billion galaxies in the universe there should be 10^15 communicable civilizations...

Maybe not in physics but millions of golfers rely on it. It's supposed to describe how hard it is to swing a golfclub. How hard it is to perform angular acceleration.

The Swing Weight of a golfclub = m * (r - 14) m = mass of the club in grams r = distance from the top of the shaft to the center of mass of the club in inches 6050 equals the swing weight D-0 But the formula for the angular acceleration of any object spinning around an axis is: ωdot = τ / I In...

1. The mass will be concentrated at the singularity. 2. Simple Newtonian mechanics apply. If the mass of the black hole is a million times the mass of the star, the black hole will hardly move at all. If it's three times the mass of the star it will move substantially.

You're oversimplifying! There's a difference between traveling 1 billion light years, then writing "crackpot" and traveling 1 billion light years, then writing the complement of a sequence you do not know until you get there.

Quantum entanglement does not imply that you can send information faster than the speed of light since you cannot manipulate what your sending. You don't know what you have until you have measured it. But you do know that you have the corresponding photon at the other location in space no matter...
