Before an impulse is received, a resting neuron is polarized with different charges on either side of the cell membrane. The exterior of the cell is positively charged with a larger number ofsodium ions present compared to the interior of the cell. The interior of the cell is negatively charged since it contains more potassium ions than the exterior of the cell. As a result of the differences in charges, an electro-chemical difference of about -70 millivolts occurs.IT means that electrical charges on the outside of the membrane is positive while inside is negative

∙ 14y agoElectrically polarised objects have had their chrages seperated, so one side will be positive, and the other side will be negative. This usually happens when an insulated object is brought close to (but doesn't touch) a charged object. Electrically charged objects will have lost or gained charge, so the whole thing will either be positive or negative. If you run a comb through dry hair a few times, it will become electrically charged. You can then use the comb to pick up some tiny pieces of paper, because the bits of paper become electrically polarised.

Is the magnesium atom electrically neutral or electrically charged?
The magnesium atom is electrically neutral.
What does 2Na mean?

How much more conductive is copper than steel?
Assuming you mean electrically, Copper is roughly 10 times less electrically-resistant than steel. That is probably the best measurement to gauge by for what you are asking.

What footwear is electrically conductive and non conductive?
what footwear is electrically conductibe or non conductive
How does an electrically polarized object different from an electrically charged object?
It will still have a electrical charge.
What is the difference between electrically charged and a neutral object?
Electrically polarized objects have had their charges separated, so one side will be positive, and the other side will be negative.
When the total charge on an object is zero the object is electrically what?
The object with zero charge is electrically neutral.
What object is not electrically neutral?
A object without electrical charges.
What object is not an electrically neutral?
A object without electrical charges.
When positive and negative charges are sparated into different parts of an object the object is said to be?
polarized
Does the space around an electrically charged object is an electric field?
yes the space around a electrically charged object is known as electric field......
When charges are separated on objects it is the?
When the charges of one object separate to opposite sides of the object, the object is polarized. It is polarization.
Where there is an equal amount of positive and negative charges on an object the object is?
Electrically neutral
A grounded electrically conductive object is forced to take the same potential as the what?
When an object is grounded it becomes electrically charged.
Why most of the object arround us are electrically charged?
There is no "why", because most of the objectsaround us are not electrically charged.
How can you charge an object electrically?
Hook it up to a battery.
