2013年8月15日 · Electrical Electrical potential Energy Potential Potential energy In summary, the problem involves finding the electric potential energy of three equal point charges placed at the vertices of an equilateral triangle with sides of length 0.600m.

2006年1月18日 · I have never dealt with negative potential energy before. dont think that energy is negative think like this there is a pt A where the charge has potential energy of 10J now when it is moved against an electric field u supply energy by doing work and move it to anothere pt B .U have supplied 5 J so now potential energy of the charge is 15J.

2010年2月20日 · The electrical potential energy (of a unit positive charge, which is how PE is defined here) between two like charges is positive if the charges are positive, and negative if the charges are negative. Between two opposite charges it can be either positive or negative depending on where you are in the field in relation to the two charges.

2021年9月23日 · Electrical potential energy is a measure of the potential energy that an object has due to its position in an electric field, while electrical potential is a measure of the electric potential energy per unit charge at a specific point in an electric field.

2017年1月19日 · In summary, the resistance of a wire in a series circuit, consisting only of 1 component (e.g. filament lamp) and a battery, is negligible; does each Coulomb of charge commit all of its electrical potential energy, supplied by the battery's potential difference, as work done across the component (thus electrical potential energy gained at battery = electrical potential …

2009年2月11日 · Charges Electrical Electrical potential Energy Line Potential Potential energy In summary, the potential energy of three charges, q1, q2, and q3, can be calculated using the equation U = k(q1q2/r12 + q1q3/r13 + q2q3/r23), where k is the Coulomb constant and r12, r13, and r23 are the relative distances between the charges.

2022年6月20日 · Potential is a property of a point in space, arising from a force field such as gravitational or electrical. Potential energy is a property of a body, or in some cases a system. The potential energy of a body at a point in space, arising from force field F, equals the potential at the point from F, multiplied by the body's property relevant to F.

2009年3月20日 · What is electrical potential energy? Electrical potential energy is the energy stored in an electric field, due to the location of charged particles. It is measured in joules (J). What factors affect electrical potential energy? The main factors that affect electrical potential energy are the amount of charge present and the distance between ...

2020年6月5日 · In summary, the conversation discusses the concept of electrical potential energy (EPE) in a system of two or three charges. The formula for EPE in a system of two charges is U = k*qQ/r, where Q is fixed. However, when a third charge is introduced, the formula becomes more complex and includes the term 1/2.

2010年2月17日 · Keep in mind that electrical potential is not the same thing as potential energy. Rather, electrical potential is the potential energy per unit charge. So you'll have to multiply the change in electrical potential by the charge (in this case -10 µC) to get the change in potential energy. Also, remember that you are dealing with vectors.
