Question

name and describe a charge process?

Explanation:

One charge process is charging by friction. When two different insulating materials are rubbed together, electrons are transferred from one material to the other. For example, when a plastic comb is rubbed with dry hair, electrons move from the hair to the comb. The comb gains electrons and becomes negatively charged, while the hair loses electrons and becomes positively charged. Another process is charging by conduction. If a charged object touches a neutral conductor, electrons can be transferred between them. For instance, a positively charged metal rod touching a neutral metal sphere will cause electrons from the sphere to move to the rod, making the sphere positively charged (if the rod is positive) or the rod can transfer electrons to the sphere if the rod is negative. A third process is charging by induction. A charged object is brought near a neutral conductor without touching it. This causes a separation of charge in the conductor (polarization), and then if the conductor is grounded (temporarily connected to the ground), charge of the opposite sign to the inducing charge flows from the ground onto the conductor. After removing the ground connection and then the inducing charge, the conductor is left with a net charge. For example, a negatively charged rod brought near a neutral metal sphere induces positive charges to move to the near side and negative charges to the far side. Grounding the sphere allows electrons (negative charge) to flow from the sphere to the ground. Removing the ground and then the rod leaves the sphere with a net positive charge.

Answer:

One charge process is Charging by Friction: When two insulating materials (e.g., a plastic comb and dry hair) are rubbed, electrons transfer between them. The material gaining electrons becomes negative; the one losing electrons becomes positive.

Another is Charging by Conduction: A charged object touches a neutral conductor (e.g., a charged metal rod touches a neutral metal sphere). Electrons transfer, so the neutral object acquires the same - sign charge (if the object is negative) or loses electrons to become positive (if the object is positive).

A third is Charging by Induction: A charged object is brought near a neutral conductor (without touching). This polarizes the conductor (charge separation). Grounding the conductor (temporarily) allows charge of the opposite sign to flow from the ground. After removing the ground and the inducing charge, the conductor has a net charge (e.g., a negative rod near a sphere induces positive charge on the near side; grounding lets electrons leave the sphere, leaving it positive after removal of the rod and ground).
