i m studying cathode ray currently, but i was confised with the
idea of voltage and current flow
i recalled that voltage is a potential difference in a circuit, which allow current flow. but as i reseach on the interent there is some site talking about negative or positve volatge??
2. i remmber that when a voltage applied, a current will flow from positive to negative
but how come cathode ray is the opposite?
thanks
