What is transposition of a transmission line?
The balancing effect on account of irregular spacing of conductors can be avoided by changing the position of the conductors at regular distances. this is called transposition of conductors. In case of 3- phase transmission lines, the inductance and capacitance of each phase will be different if the three conductors are spaced differently (each phase to the other two phases, and each phase to ground). the apparent resistance of the conductors is also affected on account of transfer of power between the phases which occur due to mutual coupling. so all the three parameters of the transmission lines are affected by irregular spacing of the conductors.
What is the meaning of mutual inductance as transformer works on the principle of mutual inductance?
Mutual inductance describes the process by which a changing current in one coil, creates a changing magnetic flux which, when it links with a second coil, induces a changing voltage into that coil.
How do you increase amperage without changing voltage or resistance?
You cannot increase amperage without changing voltage or resistance. Ohm's law states that voltage is current times resistance. You cannot change one alone. Not even changing frequency in a capacitive or inductive circuit will do this, because changing frequency represents a change in reactance, which is effectively a change in resistance.
How the breakdown voltage of a particular diode can be controlled?
The breakdown voltage of a diode, such as a Zener diode, can be controlled by adjusting its doping concentration during the manufacturing process. By increasing the doping concentration, the breakdown voltage decreases, and vice versa. This allows for precise control over the voltage at which the diode begins to conduct in the reverse-biased direction. Additionally, the physical size and structure of the diode can also impact its breakdown voltage characteristics.
What does changing the voltage or current in a circuit create?
an analog signal
What are three physical properties of changing in color of leaves?
What are physical properties of leaves changing colors
Quantiles or measured properties that are capable of changing values are called what?
Quantiles are measures of spread or dispersion. Properties that are capable of changing values are variable properties.
What is pitch in electricity?
Pitch in electricity refers to the distance between conductors in overhead power lines. It is important to maintain the proper pitch to prevent electrical arcing or short circuits. Changing the pitch can affect the electrical properties of the transmission line.
Can only determined by changing a substance?
Chemical properties can only be determined by changing a substance.
A can only be determined by changing a substance?
Chemical properties can only be determined by changing a substance.
Properties can be observed without chemically changing matter?
Physical properties such as color, shape, size, density, and state of matter can be observed without changing the chemical composition of the substance. These observations help identify the substance based on its characteristics.
Is being good energy conductors a chemical property of some metals?
it would more than likely be classed as a physical property of metals, along with colour and appearance etc. chemical properties would be more like the atomic number or the reactivity etc
Why you transpose the conductors?
Transposing the conductors in a power line reduces electromagnetic interference and power loss. By regularly changing the position of the conductors, electromagnetic fields cancel each other out, leading to improved power transmission efficiency and reduced interference with communication lines.
Why do we study physical properties first?
Physical properties can be observed or measured without changing the composition of matter.
Are properties that can be observed or measured without changing a substance into a new substance?
Yes, these are thy physical properties of substances.
When can chemical properties be observe?
chemical properties can be observed only when the substances in a sample of matter are changing into different substances
All substances have characteristic properties. If one of these properties can be observed without changing the identity of the substance it must be a?
Physical :)
