WebbV 3 = A 3 R 2 = V 1 R 2 R 2 + R 3. And. V 4 = A 3 R 3 = V 1 R 3 R 2 + R 3. We have now successfully expressed the unknown quantities in terms of the known quantities, so we are done! In the process, we used the rules from both series and parallel circuits, because this circuit is a combination of the two.

Webb9 sep. 2024 · Physically, this is telling us that as N falls off exponentially, the rate of decay falls off at the same exponential rate, because a lower N means fewer atoms that remain available to decay. Exercise 14.1.1. Check that both sides of the equation for the rate of decay have units of s − 1, i.e., decays per unit time.
