Why do you use semiconductor why not conductors and insulators by changing their properties?

We use semiconductors instead of conductors and insulators by changing their properties because the properties of a semiconductor lies between that of a good insulator ant that of a good conductor. Any of the materials obtained depends on the level of doping.

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 will you make an electromagnet stronger without changing the electric cell fitted to the circuit?
Adding more turns of wire to the electromagnet will make it stronger without changing the applied voltage.
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
Properties can be observed without chemically changing matter?
physical properties can be observed without chemically changing matter
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 Properties Can Be Observed Without Changing A Substance's Chemical Compositionion.?
All physical properties.
A can only be determined by changing a substance?
Chemical properties can only be determined by changing a substance.
Can only be determined by changing a substance?
Chemical properties can only be determined by changing a substance.
Can only determined by changing a substance?
Chemical properties can only be determined by changing a substance.
Is being good energy conductors a chemical property of some metals?
No, being good energy conductors is a physical property of some metals, not a chemical property. Chemical properties describe how a substance interacts with other substances and undergoes chemical reactions, while physical properties describe the characteristics and behavior of a substance without changing its chemical composition.
How does properties can be observed only when the substances in a sample of matter are changing into different substances?
Chemical properties
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
