A hole is a place where an electron is missing. Since the electron has a negative charge, the lack of an electron produces a net positive charge.

Does a black hole have positive or negative charge?

A black hole can have either positive, negative, or neutral charge. The charge of a black hole can be acquired through the consumption of charged particles, but the overall effect of the charge on the black hole's properties is not significant compared to its mass.


In a photocell what is the charge of a hole?

In a photocell, the charge of a hole is positive. Holes are essentially empty spaces in a crystal lattice where an electron has moved away, leaving behind a positive charge that can move through the material similar to a positively charged particle.


Why do holes migrate in direction of the applied electric field?

It might help to consider a hole as a positive particle (or rather, quasi-particle). Any positive particle gets attracted by a negative charge, and repelled by a positive charge. Of course, in reality it is the electrons that move, to fill out the hole - but the effect is the same.


Does hole exists practically in conduction of current?

A hole is a place where an electron is missing. Such places exist; and for practical purposes, it is convenient to think of them as independent positive charge carriers.


What kind of a charge does a proton have?

A proton has a positive charge.


What is a positive charge and particles called that have no charge?

A positive charge is a positive electrical charge. Particles with no charge are called neutral particles.


Protons have which type of charge?

Protons are positive (each is +1) and electrons are negative (each is -1)


Do metal ions have a positive charge?

On their own metals have no charge. Metal ions have a positive charge.

What charge do protons carry?

The proton carries a positive electrostatic charge. That charge is given as a +1 or can be expressed as 1.602 x 10-19 C.


Is b a negative or positive charge?

A positive charge


A charge on a proton?

A proton carries a positive charge of +1 elementary charge, which is equal in magnitude to the charge of an electron but opposite in sign. This charge is fundamental to the behavior of protons in interactions with other particles.
