The potential difference between the two terminals of a cell is called electromotive force in an open circuit. Electromotive force transmits current both inside and outside the cell. Electromotive force emf is the cause. Electromotive force is always greater than potential difference.
Batik (Javanese pronunciation: [ËbateÊ]; Indonesian: [ËbatÉªk]) is a technique of wax-resist dyeing applied to whole cloth, or cloth made using this technique.
Old picture frame. (Batik is normally worked on a special frame on which the cloth is tacked to keep it taut, but for beginners an old picture frame will serve just as well.) You will also need a double boiler or a boiling ring or chafing dish (such as a fondue dish with candles beneath) to melt the wax, and you will need access to a sink or bowl for dyeing.
