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.
2. Elasticity is less than One (Ed < 1): When demand is inelastic, a fall in the price of a commodity leads to fall in total expenditure on it. On the other hand, when price increases, total expenditure also increases. It means, in case of less elastic demand, price and total expenditure move in the same direction.
