The discussion centers on the potential energy of electric dipoles in relation to their orientation in an electric field. It is established that the potential energy of a dipole is conventionally set to zero at an angle of 90 degrees (where the dipole vector P is perpendicular to the electric field vector E). This is because maximum potential energy occurs when the positive end of the dipole is aligned with the electric field, which corresponds to an angle of 0 degrees. The torque is maximized at 90 degrees, but potential energy is defined relative to the lowest energy state at that angle.

if there is a maximum torque when theta = 90 degrees between angle made by the dipole vector p and the electric field vector e, why is it convention to note the potential energy of the dipole at theta = 90 degrees is 0?
Shouldn't the potential energy at theta = 90 degrees be a maximum and minimum when theta = 0 degrees (p vector is parallel with e vector)
