Pure water is an electrical insulator, but with even a little added salt, it becomes an excellent conductor. Since humans are mostly water, we are also good conductors of electricity, which is why touching someone experiencing anelectric shockcauses the toucher to experience the same shock. In ...
What is a conductor?Question:What is a conductor?Insulators:In physics, a substance that does not easily conduct electricity is called an 'insulator.' Some of the most commonly used insulators are glass, rubber, and plastic. The insulators do not allow the electrons to flow freely from one ...
An electric potential difference (a voltage) applied externally across a conductor causes an electric field inside it, and a flow of charge (a current). Conductance (the reciprocal of resistance) is current per voltage, the rate of flow of charge per potential difference. Its SI unit is the ...

What does a Conductor do? A conductor is an important figure who helps to unify and guide a musical ensemble performance, ensuring that all members of the ensemble play together in time and produce a harmonious sound. The conductor's use of gesture, facial expression, and body language helps...
Real inductors have turn-to-turn winding capacitance that acts as if it were a parallel circuit element. The self-resonant frequency (SRF) of an inductor is the frequency at which the inductive reactance is equal in magnitude to the capacitive reactance of the windings. At the SRF, the induc...

which mostly acts as a connector board without any active components. it's like the conductor directing the orchestra without playing an instrument. when should i choose an active backplane over a passive backplane? you might go for an active backplane when you need more control and intelligence...
Why is foil a good insulator? Why is cloth a good insulator? What affects the resistivity of a wire? Suppose that a (small) charged conductor is connected to the ground. Explain why the conductor becomes uncharged. Why are plastics good insulators?
