Morphology

electrostatic + charge

The noun phrase is directly compositional: 'electrostatic' (relating to static electricity) modifies 'charge' (an excess or deficiency of electrons), so a learner who knows both parts can infer it denotes an electric charge that is stationary. This follows standard scientific compounding and is cross-linguistically transparent, so the overall meaning is predictable from the constituents.

Etymology

The term electrostatic charge comes from the simple image of rubbing a balloon on your hair: small bits of electricity stay on the object's surface, so the charge can make the balloon 'stick' to the wall or your hair 'stand up'. So, electrostatic here means electric energy that 'stays' on a surface and can make nearby things 'stick' or move, which explains the phrase's modern meaning.
