If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
When the inside of a cell is negatively charged while the outside of the cell is positively charged it is known as resting potential true or false?
True.
The state during which a neuron contains more negatively charged ions inside the cell than outside the cell and is not firing is referred to as the?
resting potential
Inside the cell a lot of negative charges are present on what in the cytoplasm?
Proteins- the carboxyl group in the backbone of all proteins is negatively charged. and also some amino acid residues are negatively charged. there is also alot of phosphate groups in various forms that are also negatively charged, as well as anions such as chlorine which are stored in the cell to generate a membrane potential.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
What is the comparison between kinetic and potential?
kinetic is in motion and potential energy means it is still
What variable represents potential difference?
The variable that represents potential difference is V, which stands for voltage.
What is the electrical unit of potential difference?
Potential Difference is measured in Volts
What is a comparison of kinetic and potential energy?
They are both measured in Joules
When the outside of a nerve is positively charged and the inside is negatively charged what is this called?
action potential
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
Explain the flow of charges between two substances one is neutral and another is negatively chagred?
electrons push on each other while the difference in potential between the two substances causes them to jump across
What is the difference between electrical potential and electromotive force?
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.
What is the potential difference measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
What is the potential voltage?
Unless you are using 'potential' in the general sense (i.e. "What is the possible voltage?"), there is no such engineering term as 'potential voltage'. Voltage is a synonym for 'potential difference', so your expression would then mean "What is the potential potential difference?"Do not mix up 'potential' with 'potential difference' (voltage); they are two different things.
What can be converted to energy?
Anything with potential difference could create the flow of energy. A potential difference could be electropotential, chemical potential or potential difference between high and low ground like energy from water fall. A potential difference can exist in the form of motion difference between a stationary and a moving objects.
When an electron is brought near a negatively charge plate its electric potential energy is?
As an electron is brought closer to a negatively charged plate, its potential energy increases. Since like charges repel, the electron has to be "brought" near the negatively charged plate ... it'll never go there on its own. You have to push it there, meaning you have to do work on it, and that work adds to the potential energy of the electron. As soon as you let it go, it'll whizz AWAY from the negatively charged plate, and that energy you put into it will turn into the kinetic energy of a hasty retreat.
