Video transcript

Welcome back everybody. We have the electrical circuit presented before us and we are told that the capacitance of this first capacitor is 10 PICO Fair adds that. The capacity of the second capacitor is seven PICO Fair ads and the third eight PICO Fair ads. And we are tasked with finding what the equivalent capacitance is between the points L. And M. Now between L and M. We only have these two capacitors that are in parallel. So really what we're looking for is the equivalent capacitance of capacitors two and three. Now, since they are in parallel, all we do is just add the capacitance of the individual capacitors. So we will have seven plus eight PICO Fair adds to give us our final answer of 15 PICO Fair adds corresponding to answer choice. C. Thank you all so much for watching. Hope this video helped. We will see you all in the next one.
