What is an ebonite rod?
an ebonite rod is a solid in which you find little black phosterus in
When a ping-pong ball is made to touch a charged plastic rod it is attached and then repelled?
yes , because the positive charge are attach in it
What is surging in compressor?
Centrifugal and axial compressors will surge when forward flow through the compressor can no longer be maintained, due to an increase in pressure across the compressor, and a momentary flow reversal occurs. Once surge occurs, the reversal of flow reduces the discharge pressure or increases the suction pressure, thus allowing forward flow to resume again until the pressure rise again reaches the surge point. This surge cycle will continue until some change is made in the process or compressor conditions.
What conditions are necessary for a magnetic field to produce a force on a wire?
To answer this question, let's look at the definition of the following words. Voltage, Current, and Resistance One volt is one joule of energy per coulomb of electrons. One ampere means one coulomb of electrons is moving through the wire each second. R = V ÷ I = J/s ÷ C/s = J/C The resistance measures the amount of energy that is required to make one coulomb of electrons move through the wire. The charge of one electron is 1.6 * 10^-19 C. To determine the number of electrons per coulomb, invert this number. Number of electrons per coulomb = 6.25 * 10^18 One ampere means 6.25 * 10^18 electrons are moving through the wire and resistor each second. If the resistor is one ohm, one volt will be required for this to happen. To determine the amount of charge that is moving in a wire each second, you will need to wire's resistance and the voltage that is being used. Voltage and resistance determine the amount of charge that is moving through the wire each second. I hope this answers your question.
Why is welding rod kept in a rod oven?
to keep moisture out
Is ebonite charged?
yes ebonite rod is charged and it has positive charge on it.
What happens when rub an ebonite with a wool cloth?
The ebonite rod will gather a static electric charge, as electrons are transferred.
What kind of charge is induced on a metal-leaf electroscope by an ebonite rod?
Static
What is an ebonite rod?
an ebonite rod is a solid in which you find little black phosterus in
How can a conductor be made to hold its charge?
It is not possible to make a ordinary conductor hold it's charge permanently.But you can make a ordinary conductor(e.g.,)a wire to hold charge for a short period.This is because a charge stored in a conductor leaks to the surroundings due to ionisation of air. But it is possible to charge a conductor like a copper sphere. for this the copper sphere is first connected to ground and a negatively charged ebonite rod near it.the copper sphere becomes positive as the negative charges in it flow to the ground.the sphere is disconnected from ground and the ebonite rod is taken away.now the copper sphere holds positive charge. note: it is easy to charge an ebonite rod by rubbing it with fur.
When a ebonite rod rubbed with funnel is bought nearer to another ebonite rod what happens?
it attracts it
Where do you use ebonite rod?
ebonite rod is a thin, round stick made of hard, black rubber.
What happens when you rub vinyl with wool cloth?
You build a charge when rubbing vinyl with a wool cloth. The wool cloth is very weak in holding electrons so when you rub it with the ebonite rod the electrons transfer onto the rod. The rod is negatively charged (assuming that the rod was neutrally charged). The wool becomes positively charged (assuming that the wool was neutrally charged)
Where does the excess charge on a copper rod flow to if you don't use an insulator?
If you connect the rod with a conductor, part of the charge will flow to the conductor.
What is Ebonite?
Hard rubber. It's named after the bowling ball company that invented it.
What happens when ebonite rod rubbed with flannel?
no
What happens when a charged ebonite rod is brought close to water?
Ebonite rod becomes positively charged and the fur becomes negatively charged. Hold on electrons: Fur > Ebonite rod So, the ebonite rod loses its electrons to the fur and the fur becomes negatively charged.
