The magnitude of the electric potential is dependent upon the particle's charge and the electric field strength.
Yes. Electric Potential energy E= VQ thus 2VQ = 2E.
Temperature
This answer depends on who you are asking some people say it flows from negative to positive and others say its the other way around but really it doesn't matter that much because normal 60Hz AC changed direction 60 times a sec
frequency
Independent means that it is a variable that is unaffected by other variables. For example, in terms of acceleration, velocity is the dependent variable, and time is the independent variable. Velocity is dependent upon time, but time is not dependent upon velocity. Of course, technically speaking, this is only for nonrelativistic scenarios. If velocity is extreme (near the speed of light) time IS affected by velocity in spacetime. But, that's a different issue.
The magnitude of the electric potential is dependent upon the particle's charge and the electric field strength.
Gravitational potential energy.
Dependent upon how power derived.
gravitational potential energy
That is called gravitational potential energy.
weight times height
That is called gravitational potential energy. Sometimes simply "potential energy", and the "gravitational" part is implied.
Electric potential is a scalar.
Potential engergy is the engergy an object has based upon the height from the ground. Electric current also seeks an electrical ground. The symbols and equations are quite similar as I recall in my Physics.
Electric potential is the electric potential energy per unit coulomb. So unit for electric potential is J/C and that of electric potential energy is simply J
Electric field is dependent on the magnitude of the electric charge, E = qzc/r2
Dimension for Electric potential is [ML2T-3I-1]
