Write an equation of the cosine function with amplitude two thirds period 1.8 phase shift -5.2 and vertical shift 3.9?
y=2/3cos(1.8b-5.2)+3.9
In single phase 1 TR equals how many KW?
1TR = 3.5KW in Single phase and 1.2KW in 3-phase
A steep slope on a phase change graph indicates?
A steep slope on a phase change graph indicates a rapid change in temperature with respect to the amount of heat added or removed from a substance. During a phase change, such as melting or boiling, the temperature remains constant while the substance transitions between states of matter. The steep slope represents the energy required to overcome the intermolecular forces holding the particles together in a particular state.
A horizontal line on a phase change graph indicates?
A horizontal line on a phase change graph means there has been no change. Often longer periods of research are needed to see significant change.
Is 1 kva 1 kw?
Yes, if the power factor (cosine of the phase-angle between voltage and current)is ' 1 '. In order for that to be true, the total load impedances on the line have tobe pure resistive, with zero reactance.All of this stuff applies only on an AC line. On a DC line, voltage and current arealways in phase, the power factor is 1, and KVA = KW .
