Question
An electron in a TV is accelerated toward the screen across a potential difference of 52.8 kV. How much kinetic energy does the electron gain while accelerating?
How would you solve this?

52.8 * 10^3 * electron charge
Voltage is electric field E times distance
Force is E q
Force times distance = work = energy gain = E q * distance = V q
That is why they call voltage "potential" :)
