Bina plug lagaye aapke phone ki screen kaise chal pati hai? Aapke phone ki battery ke andar hone wale rasayanik badlav hi iska jawab hain. Electrochemistry, yani rasayan aur bijli ke beech ka sambandh, isi ko samjhati hai. Battery mein hone wala badlav electrons ko chalata hai. Phone istemal karte samay, ye electrons battery se bahar phone ke circuit mein bahte hain aur use chalate hain. Is badlav ko redox kehte hain: ismein electrons ek jagah se doosri jagah jate hain. Lekin electrons bahari circuit mein chalte hain; battery ke andar ions chalte hain. Unki aawajahi aavesh ka santulan banaye rakhne mein madad karti hai, jisse bahari pravah jari reh sake. Battery bijli ki taiyar dhara nahi chhodti. Uska rasayanik badlav poore circuit mein aavesh chalata hai. Phone ki screen isliye chalti hai: battery ki rasayanik pratikriyaen vidyut dhara chalati hain. Electrons taron mein bahte hain, jabki ions andar chal kar aavesh santulit karte hain.
