Creepage distance in insulators?
It is the shortest distance between the conductors measured along with the surface of insulators.
What two conductors feeding a load have capacitance?
Two conductors feeding a load that have capacitance are typically a pair of parallel wires or a twisted pair of wires. The capacitance arises due to the electric field created between the conductors, which can store electrical energy. This phenomenon is significant in high-frequency applications, where the capacitance can affect signal integrity and transmission efficiency. In such cases, understanding and managing the capacitance is crucial for optimal performance.
What is the Relationship between length of cable and capacitance?
The capacitance of a cable is directly related to its length; as the length of the cable increases, the capacitance also increases. This is because capacitance is determined by the surface area of the conductors and the distance between them, with longer cables providing more surface area for charge storage. Additionally, other factors such as the dielectric material between the conductors and their geometry also influence capacitance. Overall, longer cables typically exhibit higher capacitance values, impacting signal integrity in electrical systems.
What is the difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
How do you calculate 3X120sq.mm PILC cable capacitance?
To calculate the capacitance of a 3X120 sq.mm PILC (Paper Insulated Lead Covered) cable, you can use the formula for the capacitance per unit length of a three-core cable, which is approximately ( C = \frac{2\pi \epsilon}{\ln(\frac{D}{r})} ), where ( \epsilon ) is the permittivity of the insulation material, ( D ) is the distance between the conductors, and ( r ) is the radius of the conductor. The total capacitance can then be derived by multiplying the capacitance per unit length by the length of the cable. Specific values for ( \epsilon ), ( D ), and ( r ) should be obtained based on the cable's construction and insulation type.
Does capacitance exists between two current carrying conductors?
Capacitance exists between any two conductors, current carrying or not.
What is the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
Are scissors conductors?
They are Conductors, not much for insulation though. Differences between conductors and insulators? Conductors let energy such as electricity .
Creepage distance in insulators?

Substance in between conductors and insulators used in transistors?
Semiconductors
Materials that are not good conductors or and not good insulators are called?
Semiconductors. They have conductivity between conductors and insulators and are used in electronic devices like transistors and diodes.
How are materials classified on the basis of resistivity?
Materials can be classified based on their resistivity as conductors, semiconductors, or insulators. Conductors have low resistivity, allowing electric current to flow easily. Semiconductors have resistivity in between conductors and insulators, and their conductivity can be controlled. Insulators have high resistivity and do not allow electric current to flow easily.
What are Conductors Insulators Semiconductors?
Conductors are materials that allow electricity to flow easily, like metals. Insulators are materials that do not allow electricity to flow, like rubber or glass. Semiconductors are materials that have properties between conductors and insulators, and are commonly used in electronics.
Does capacitance exist between two thin current-carrying conductors Explain?
The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like the dielectric medium between them.A capacitor is a device used to store electrical charge and electrical energy.
Difference between stray and parasitic capacitance?
Parasitic capacitance is unavoidable and usually unwanted capacity between two or more conductors which exists due to close proximity and which typically causes non-ideal circuit behavior. Stray capacitance, as it is typically thought of, is a type of parasitic capacitance. It is the capacity from a conductor to its surroundings which is the aggregate of the conductors in its environment inversely weighted by the distance to each of the environmental conductors.
How do you know the difference between conductors and insulators?
Conductors allow the flow of electricity due to the presence of free electrons, while insulators inhibit electron flow. Conductors often have low resistance, while insulators have high resistance to the flow of electricity. Materials such as metals are good conductors, while materials such as rubber are good insulators.
