Connect the red wire to the positive (+) terminal of one of the cells, and connect the black wire to the negative (-) terminal of the other cell. Later, as a last step, you will connect a wire between the negative (-) terminal of the first cell and the positive (+) terminal of the other cell.
Inelastic market conditions occur when the supply or demand of a good is relatively resistant to changes in price. Economists sometimes use the term qualitatively to describe goods in the marketplace, but may also apply mathematical formulas to quantify the degree to which market conditions are elastic or inelastic.
Supply is elastic if the price elasticity of supply is greater than 1 (es > 1), unit elastic if it is equal to 1 (es = 1), inelastic if it is less than 1 (es < 1), perfectly elastic when a small change in price changes the quantity supplied by an infinite amount (es = Ã¢ËÅ¾) and perfectly inelastic when the quantity supplied is unaffected by a change in price (es = 0).
