Does the answer make complete sense? I want to make sure you understand how what I just said comes directly from the definition of the eV.Originally posted by soso
Warren- thank you so much for your help.. ur a life saver.. i really appreciate it.. take care.
The potential difference, also known as voltage, is directly proportional to the electron energy. This means that as the potential difference increases, so does the electron energy, and vice versa.
The equation is E = qV, where E is the electron energy in joules (J), q is the charge of the electron in coulombs (C), and V is the potential difference in volts (V).
To convert from volts to joules, you simply multiply the potential difference by the charge of the electron. The resulting unit will be in joules.
Yes, potential difference can have a negative value. This indicates that the electrons are moving in the opposite direction of the electric field, and their energy is decreasing.
The potential difference creates an electric field that exerts a force on the electrons, causing them to move. The greater the potential difference, the stronger the electric field, and the faster the electrons will move.
