in a circuit when battery flow electricity from positive terminal but chemicals flow from negative terminal. give reasons Share with your friends Share 1 Pintu B. answered this Dear Student , Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.So the current flows in opposite direction of electron flow .This is why hence current flows from positive terminal to negative terminal and the chemicals flow fromnegative terminal to positive terminal of a battery . Hope this helps you .
