An electron is accelerated through a potential difference of 10000v

Summary • Define electric potential and electric potential energy. • Describe the relationship between potential difference and electrical potential energy. • Explain electron volt and its usage in submicroscopic process. • Determine electric potential energy given potential difference and amount of charge. When a free positive charge q is accelerated by an electric field, such as shown in q by the electric field in this process, so that we may develop a definition of electric potential energy. Figure 1. A charge accelerated by an electric field is analogous to a mass going down a hill. In both cases potential energy is converted to another form. Work is done by a force, but since this force is conservative, we can write W = –ΔPE. The electrostatic or Coulomb force is conservative, which means that the work done on q is independent of the path taken. This is exactly analogous to the gravitational force in the absence of dissipative forces such as friction. When a force is conservative, it is possible to define a potential energy associated with the force, and it is usually easier to deal with the potential energy (because it depends only on position) than to calculate the work directly. We use the letters PE to denote electric potential energy, which has units of joules (J). The change in potential energy, ΔPE is crucial, since the work done by a conservative force is the negative of the change in potential energy; that is, Work = – ΔPE For example, work, symbol W, done to...

\( \newcommand\) • • • • Learning Objectives By the end of this section, you will be able to: • Define electric potential and electric potential energy. • Describe the relationship between potential difference and electrical potential energy. • Explain electron volt and its usage in submicroscopic process. • Determine electric potential energy given potential difference and amount of charge. When a free positive charge \(q\) is accelerated by an electric field, such as shown in Figure \(\PageIndex\) to make \(W\) positive. PE can be found at any point by taking one point as a reference and calculating the work needed to move a charge to the other point. POTENTIAL ENERGY \(W=-\Delta \mathrm.\] ELECTRIC POTENTIAL This is the electric potential energy per unit charge. \[V=\dfrac\] POTENTIAL DIFFERENCE The potential difference between points A and B, \(V_=q\Delta V.\] POTENTIAL DIFFERENCE AND ELECTRICAL POTENTIAL ENERGY The relationship between potential difference (or voltage) and electrical potential energy is given by \[\Delta =\dfrac=q\Delta V.\] The second equation is equivalent to the first. Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since \(\Delta PE=q\Delta V\). The car battery can move more charge than the motorcycle battery, although both are...

i am just wondering, is it possible to find the velocity of a single electron that is accelerated by a certain potential difference? Also I am having trouble with this homework problem: A coil with a magnetic moment of 1.40 A*m^2 is oriented initially with its magnetic moment antiparallel to a uniform magnetic field of magnitude 0.845T. What is the change in potential energy of the coil when it is rotated 180 degrees so that its magnetic moment is parallel to the field? I remember that antiparallel means when two vectors just have the same direction cept that they are opposite signs so wouldn't the change in PE just be 0? I'm not too sure about that one. Yes. You can find the velocity of an electron accelerated through a particular potential difference. Remember that: potential differerence (aka voltage) * charge = Change in potential energy (U)... Since you know the charge of an electron...you can simply multiply this by the potential difference to figure out the energy change. KE = U Now, since KE = 1/2 mv^2 ...you can plug in and solve for velocity. Yes. You can find the velocity of an electron accelerated through a particular potential difference.
