The electric field points from higher potential to lower potential. A positive charge particle will follow the electric field losing potential energy. When a positive charge is moved against the electric field, work is done on it that increases its potential energy.
a) If a proton moved from a location with 5.0v potential to a location with 7.5v potential, would its potential energy increase or decrease?
b) If an electron moved from a location with 7.5v potential to a location with 5.0v potential, would its potential energy increase or decrease? Explain in detail.
