A cathode is negative. It attracts cations, which are positively charged.
It is a negatively charged object
It is positively charged because of the protons.
We call this Conventional Current Flow, where imaginary positively charged particles are repelled away from a positive charge and attracted towards a negative charge.The reality is that electrons are actually flowing through the conductor. Electrons are negatively charged particles and flow from negative to positive. It's just easier to think of a positive current flowing than a negative current.
Negative * positive = negative Positive * positive = positive Negative * negative = positive
