What is the amount of energy gained by a proton accelerated through a potential difference of 50 V?
The charge of proton 'e' is 1.602 x 10--19 C.
If it is subjected to a potential difference of 50 V, then the electrostatic potential energy gained by that proton will be 50 eV.
To get the energy in joule, replace 'e' by 1.602 x 10 --19.
Then, the required value is 8.01x10 --19 J
eV is the unit of energy which will be more convenient while dealing with very very small amount of energy. 1 eV = 1.602 x 10 --19 J

What is single electrode potential?
An electrode potential is the potential difference that develops when an electrode of one element is placed in a solution containing its ions. In a galvanic cell, electricity is produced by the electrode potential of the two metal electrodes and their corresponding electrolytes.
What electricity refers to the electrical charge an object develops as a result of having an unequal amount of protons and electrons?
Electricity refers to the flow of electric charge through a conductor. This charge can result from an imbalance of protons and electrons in an object, creating a difference in electrical potential that can drive the flow of electrons.
Which moleclues holds the greatest amount of potential energy?
Molecules with a high number of carbon-hydrogen bonds, such as those found in fats, hold the greatest amount of potential energy because they have many electrons available for bond formation. This energy can be released through chemical reactions in the body to provide fuel for cellular processes.
How can 9.0V batteries could have different potential energy?
Short answer: Voltage is not a complete measure of potential energy any more than the height of a weight is a complete measure of potential energy. In order to calculate energy you must multiply the voltage by the amount of current (Amps) that can be supplied to get power. Then you multiply that power by the amount of time it can be supplied to get energy (power is energy per unit time). to get the potential energy of a weight suspended above the ground you must multiply the height of the weight by it's mass and multiply that by the gravitation acceleration (about 9.8 meters per second squared on earth). Long answer: A 9V dry cell in a radio may only supply 111 milliamps for an hour or so while a 9V golf cart battery can supply 111 amps for an hour. Therefore the radio battery has a potential energy of 3.6 Kilojoules while the golf cart battery has 1000 times that amount, 3.6 Megajoules. Since a joule is equivalent to one kilogram accelerated over one meter at 1 meter per second squared and gravitational acceleration is 9.8 meters per second squared 3.6 Megajoules is about the same potential energy as a 1000 Kg (2200 pound) car at the top of a 367 meter (1200 feet) hill. The 9V battery has the potential energy of the same car .367 meters (1 foot 2.4 inches) up the hill. Quite a difference in potential energy.
What is the difference between .05mg and .075mg?
The difference between 0.05mg and 0.075mg is 0.025mg. This means that 0.075mg is a higher dose than 0.05mg by 0.025mg. The numerical value represents the amount of medication in milligrams.
What is the relationship between the potential difference across a capacitor and the amount of charge stored on it?
The potential difference across a capacitor is directly proportional to the amount of charge stored on it. This means that as the potential difference increases, the amount of charge stored on the capacitor also increases.
What is the relation between 1 electron volt and 1 joule?
1 electron volt (eV) is equal to the amount of energy gained by an electron when it is accelerated through a potential difference of 1 volt. This energy amount is approximately equal to 1.6 x 10^-19 joules.
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 how potential difference in a battery is similar to a staircase?
The potential difference in a battery is like the height of the stairs. The amount of charge separated in a battery is like the mass moved up the stairs. The potential energy in the battery is due to both the potential difference (volts) and the amount of charge that has been separated (coulombs).
In physics what is an electron volt?
In physics an electron volt is a very small unit of energy. An electron volt is the amount of energy gained by the charge of an electron once it has moved across an electric potential difference of one volt.
One million electron volts is equal to?
One million electron volts (1 MeV) is equal to the amount of energy gained by an electron when accelerated through a potential difference of one million volts. This unit is commonly used in particle physics to express the energy of particles.
Why is potential difference measured in volts?
Potential difference is defined as follows: every coloumb of charge that passes through this difference will gain (or lose, depending on direction and signs) 1 joule of energy. This unit, joule/coloumb, is simply called the volt.
How can works capacitors?
When connected to a d.c. supply, electrons are transferred from one plate and deposited on the opposite plate. This creates a potential difference across the two plates. This action continues until the capacitor's potential difference is equal (but opposite) to the potential difference of the d.c. source. If the source is then removed, the electrons cannot return to the original plate, other than through the dielectric, so the capacitor will hold that potential difference. By definition, the charge 'stored' on the capacitor is the amount of negative charge on the negative plate (not the sum of the charges on the two plates). Leakage current through the dielectric gradually reduces the potential difference across the plates.
One way to make current is to use a what?
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
Is voltage measured in volts?
Voltage, along with electric pressure, electric tension, and electrical potential difference is measured in units of electric potential. This can be joules per coulomb or volts.AnswerFirst of all, there is no such thing as a 'voltage difference'. Voltage is already a 'difference', as it is an alternative name for 'potential difference'! 'Voltage difference', therefore, would mean 'potential difference difference', which makes no sense!The unit for potential and potential difference (voltage) is the volt, which is equivalent to a coulomb per second.
The volt is the unit of electric?
Yes, the volt is the unit of electric potential or electromotive force. It represents the amount of potential energy per unit charge.
What is the amount of electrical pressure in a circuit?
The amount of electrical pressure in a circuit is measured in volts (V). It represents the potential difference between two points in the circuit and is responsible for pushing the electric current through the circuit.
