Reactance is the property of an electrical component to oppose the change in current while impedance is the combination of resistance and reactance. There are two types of reactance: Capacitive & Inductive

homeostasis is quite crucial for the survival of organisms. it is often seen as a resistance to changes in the external environment. furthermore, homeostasis is a self-regulating process that regulates internal variables necessary to sustain life. in other words, homeostasis is a mechanism that ...
motion and behavior of an object through space and time, matter and its fundamental constituents." In simple words, it can be said that physics is one of the most fundamental disciplines of science, and its ultimate goal is to understand how the universe...
What is the moment of inertia? What is moment of inertia? How can it be so hard to drag rubber across smooth glass if friction is caused by surface roughness? How do you account for inertia, elasticity and frictional resistance for the flow of electromagnetic waves?
nb: Note (at 1:20s) how steam delivered the future we now enjoy, and how clearly he warns of the dangers of ending progress using the precautionary principle, resistance to all change to preserve the ruling classes control of people and money, that religion had imposed for so long by fear...
The simplest way to exercise with a resistance cord is to take one end of the cord in each hand, and stretch the cord out to each side of the body. This simple method ofstretchingalso works by placing the middle of the resistance cord under the feet, and pulling up with each hand as...
A unit of electrical energy equal to the work done when a current of one ampere passes through a resistance of one ohm for one second 1 Watt In the International System of Units, the derived unit of power; the power of a system in which one joule of energy is transferred per second. ...
What is ohm's law? Explain in simple words. What is the resistance of frustum having length 'l' and radii a and b ? What does it mean for one force to be stronger than another? What are the purposes in ohmic and non ohmic devices ?
Resistivity is the electrical resistance of a conducting material per unit length. In other words, it is the degree to which a conductor opposes the flow of electricity through itself, instead allowing the energy to flow out of the electrical circuit, most often as heat. Resistivity is useful ...
