These two words are used differently as shown below: Electric engineering (incorrect✖) Electrical engineering (correct✓) Electrical lamp (incorrect✖) Electric lamp (correct✓) And sometimes, they're used interchangeably as shown below: Electric appliance (correct✓) Electrical appliance (correct✓) I am curious to know how these words are used correctly, how to know which one to use, for instance, with 'substation'.
