常見錯誤

❌I left the phone with an uncharged battery overnight.
✅I left the phone with a dead battery overnight.
💡uncharged describes something that has never been given a charge, whereas dead battery means it was charged but has lost its power.
❌The uncharged particle was neutral and carried equal positive and negative forces.
✅The uncharged particle was neutral and carried equal positive and negative charges.
💡uncharged already means 'no net charge'; adding 'neutral' is redundant with the definition.
