Potential difference, also known as voltage, is the difference in electric potential between two points in an electric field. It is measured in volts (V) and is the driving force for the flow of electric current.
Potential difference can be calculated using the equation V = KE/q, where V is the potential difference, KE is the kinetic energy of the charged particle, and q is the charge on the particle.
The relationship between frequency and potential difference is directly proportional. This means that as the frequency of the electric field increases, the potential difference also increases.
Potential difference is the driving force for the motion of charged particles. The higher the potential difference, the greater the force on the charged particles and the faster they will move.
Yes, potential difference can be negative. This means that the direction of the electric field is opposite to the direction of the charged particles. It is important to note that the magnitude of the potential difference is still the same, regardless of its sign.
