How are electric charges measured?
Electric charges are typically measured in units called coulombs (C). One coulomb is equivalent to the amount of charge flowing past a given point in one second when the current is one ampere. Instruments such as an ammeter or a coulomb meter can be used to measure electric charges.
Will gold allow electric charges to flow easily in a cumputer part?
Gold is a good conductor of electricity, so it can facilitate the flow of electric charges in computer parts. This is why gold is often used in connectors and other components where reliable conductivity is crucial for smooth operation.
What are electrical charges that are not in motion?
Electrical charges that are not in motion are usually stationary and form an electric field. This stationary state can occur in objects that are insulated or in a closed circuit where there is no movement of charges. The potential energy of these stationary charges can be harnessed and used in various electrical applications.
Do magnets affect electric?
Yes, magnets can affect electric currents and vice versa. Moving electric charges create magnetic fields, and magnetic fields can induce electric currents in conductors. This relationship is fundamental to electromagnetism and is used in many technologies, such as electric motors and generators.
Why is magnetic field used to deflect electron beam and not an electric field in a television picture tube?
A magnetic field is used to deflect an electron beam in a television picture tube because it can act on moving charged particles (like electrons) without requiring contact, making it suitable for controlling the beam's path. Additionally, using an electric field alone would cause the electrons to accelerate or decelerate due to the force, affecting their speed and the resulting picture quality.
Which scientist used the cathode ray tube to isolate the electron in 1897?
J.J. Thomson used the cathode ray. Thomson's cathode ray experiment was when he shot a narrow beam of electrons through a cylindrical tube and deflected the electrons off of electric and magnetic fields, thus measuring the effects that those fields had on the direction of the beam.
What can be used to absorb electric charges?
seeds
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.

What is a material that readily allows electric charges to pass through it?
Copper is very good conductor of electric charge. That is why it is invariably used in the electric motors.
What is the Difference between dielectric and insulator?
The difference between dielectric and insulator lies in its field of application.Dielectrics are used to store the electric charges, while insulators are used to block the flow of electric charges ( they more or less act like a wall).While all dielectrics are insulators (they don't allow the flow of electric charges through them) all insulators aren't dielectric because they can't store charges unlike dielectrics.
What are some real life examples of electric charge?
Static electricity, lightning, and the electricity used to power appliances are all electric charges.
What is example of beam matter?
Perhaps a simple example is in electric arc welding, where the electric arc is used to transfer the metal from the welding rod onto the workpiece. You may consider the arc (plasma) to be a type of beam, though it only operates over a small distance.
Who used a cathode ray tube to study matter?
you may wonna check this but i believe it was j.j Thomson
What process can be used to visualize the electric field between two charges?
You can use Conformal Mapping-see the related link.
How did Thomson know that the glow in the crt was from a stream of charged particles?
Thomson observed deflection of the glow by magnetic and electric fields, which suggested a charged particle. He further confirmed this by measuring the charge-to-mass ratio of the particles using the deflection in the presence of known electric and magnetic fields.
