Question
Pressure Difference causes electricity to flow. a. The pressure difference across a component is the product of the flow through a component and the obstacle presented to it. b. The pressure difference across components that are wired in parallel is the same. c. The sum of pressure differences around a loop that joins one end of the battery to the other is a constant that is a characteristic of the battery. The loop doesn't go through any points more than once: the pressure difference across a component (that is in parallel with others) is only counted once. There is more to be said about pressure difference that we found in electricity V. Consider the following question. Is it possible to say anything about pressure difference across components that are in parallel? If the two components are the same then we can use symmetry; Since both branches have obstacles that are the same, the flow through each branch must be the same. Remembering the definition, pressure difference = flow * obstacle, what is the relation between the pressure difference (product) across the component on the left compared with the pressure difference (product) across the component on the right? Explain.Explanation / Answer
Pressure difference across both branches in parallel will be same
As stated pressure difference = flow * obstacle
Since obstacle is same, so is flow
Hence
Pressure difference left = Pressure difference right
