Is magnetising current affected by load? Magnetising current flows into the primary irrespective of transformer load condition. Why magnetizing current is important? A certain amount of current is drawn by a transformer from the source connected to it primary even when no load is connected to its secondary. A part of this current is used […]

How do you show a force is conservative?
How do you show a force is conservative? Equivalently, a force is conservative if the work it does around any closed path is zero: Wclosed path=∮→Econs⋅d→r=0. What are conservative forces give two examples? Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force. Other examples of […]
Is symbiosis important to an ecosystem?
Is symbiosis important to an ecosystem? Symbiotic relationships are important because they are a major driving force of evolution. This networking and cooperation among species allows them to survive better than they would as individuals. How can symbiosis hurt the ecosystem stability? In symbiotic relationship such as mutualism and commensalism, both the organism survived and […]
What are the 5 steps to achieving equilibrium?
What are the 5 steps to achieving equilibrium? This 5-step process works like this: Nuclear fusion. Out of fuel. Fusion stops, temperature drops. Core contracts (gravity pulling atoms in). Increased temperature (more atoms, more collisions) and density in the core reinitiates nuclear fusion, equilibrium is achieved, and the cycle begins again at step 1. What […]
