What is the size of the paddles? What is the conclusion from these studies? Why did we do this study?


Points of data were taken in 5 minute intervals increasing the threshold by ten mV each time. This means that x is equal to ten mV in these trials. The data received in each interval is equal to the figure A (Area). This is the area of the interval under the curve over the distance x. To find the hight (h), the area A is divided by the distance x.
