negatively earthed
hello folks
is a correct statement that whenever the POH says that the electrical system is negatively earthed it means that the negative pole of the battery is grounded to the airframe - i guess a wire stretching from the post to the airframe -, so that as electricity is the flow of electrons from the negative to the positive post, electricity will travel from the negative post to the positive one, then to a bus bar from where it is made available to the component. the singular component is then grounded to the airframe to cmplete the circuit, allowing the electrons to use the chassis as a connection allowing the electrons to flow back to the negative post?
how does this apply to the DC generator - alternator with slip rings?
when diodes are used instead of slip rings, how do they revert the polarity turning it into DC?
many thanks
