Is the electric field zero or nonzero in a region of space if the potential is constant throughout this given region?
if the potential is constant throughout the given region of space then delta v=0, then by equation E=-delta v/delta r, E will be zero.
If potential is constant throughout a given region of space can you say that electric field is zero in that region?
If the electric field is zero, the electric potential is a constant value, but it does not tell you what that value is. All the electric field tells you is how the electric potential changes within the region you are looking at. If the electric potential at one end of a cylindrical region is 7 V and the electric field is zero within the whole cylinder, then the electric potential is 7 V at the other end, or somewhere in the middle, or on the side, and so forth. An electric field of zero tells you the potential does not change, but doesn't say anything about what it is outside of the region you're looking at.
What is the difference between electron flow direction and electric current flow direction?
the electrons flow from the region of low potential to region of high potential. the electric current also flow in this direction but for convention we took it as the flow of positive charge from region of low to high region potential.
What is no flux condition?
Flux means the rate of change of magnetic field lines through a particular region in space. Magnetic field lines are imaginary lines drawn to demonstrate the magnetic field through a region in space. No flux condition means the magnetic field lines in the observed region in space is uniform throughout the experiment.
Do electrons tend to go to region of high potential or of low potential?
Electrons tend to go to an area of low potential to high potential. This is because an area with high potential is more positive and the charge on an electron is negative.
Is the electric field zero or nonzero in a region of space if the potential is constant throughout this given region?
if the potential is constant throughout the given region of space then delta v=0, then by equation E=-delta v/delta r, E will be zero.
What is an osmosis?
Osmosis is the random movement of water molecules through a semi-permeable membrane from a region of high water potential to a region of low water potential.
What is the defintion of osmosis?
The net movement of solvent molecules from a region of high solvent potential to a region of lower solvent potential through a partially permeable membrane

How osmosis works?
Osmosis is the net movement of water molecules from a region of higher water potential to a region of lower water potential through a partially-permeable membrane.
How does the potential difference in the resistor change as the current through it changes?
The potential difference accross the resistor changes mainly due to gradual increase accumulation of electrons in the lower potential region which will in turn affect the potential gradient as the current flows through the resistor
What is potential barrier factor?
Potential barrier is the energy inserted in order to go against the passage of electron.
Do electrons tend to go to region of high potential to region of lower potential?
electrons tend to go to the region of high potential because they are of negative charge.
When air pressure is constant throughout a region of the atmosphere the region is in a state is called what?
When air pressure is constant throughout a region of the atmosphere the region is in a state is called equilibrium.
What is osmosis?
osmosis is a movement of a fluid that passes through a semipermable membrane
Which membrane potential occurs because of the influx of Na plus through chemically gated channels in the receptive region of a neuron?
An excitatory postsynaptic potential, a type of graded potential, occurs because of the influx of Na+ through chemically gated channels in the receptive region, or postsynaptic membrane, of a neuron. Graded potentials are generated by chemically gated channels, whereas action potentials are produced by voltage-gated channels.
