After half a second, we should each be pointing to: starting point + amount traveled = 45 + 180 = 225 degrees (on a 2-inch circle). When connecting two systems with slightly different phase angles, there will be net neutral current that would flow in the ground/neutral that interconnects the two sources. In the first case, the two have the same phase. the integral of the sinusoidal current is a negative cos function: it reaches

In other words, the two alternating quantities have phase difference when they have the same frequency, but they attain their zero value at the different instant. These phenomena also have applications such as Cornu spiral and Fresnel biprism. For more details about this phenomenon, and a discussion

That way, you can still move around while attacking, but the attacking animations have higher priority and play in entirety. If we’re using a polyphase voltage source to power resistive loads, phase rotation will make no difference at all. Our goal is to stop those embers from turning into another blazing fire. The particle velocity and pressure are in-phase; positive velocity (moving right) occurs when pressure is positive (compression). phase?
