An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave.
Elasticity of supply measures how the amount of a good changes when the producer hires more employees. Elasticity of supply measures how the amount of a good changes when the producer uses new materials. Elasticity of demand measures how the amount of a good changes when its price goes up or down. Elasticity of demand measures how the amount of a good changes when its distribution expands.
According to geometric method, elasticity is measured at a given point on the supply curve. This method is also known as âArc Methodâ or âPoint Methodâ. The measurement of elasticity of supply for the supply curve SS (say, at point A) is illustrated in Fig. 9.20:
