An L-R-C series circuit has L = 0.600 H and C = 3.00 mF. (a) Calculate the angular frequency of oscillation for the circuit when R = 0.

Video transcript

Welcome back, everybody. We are making observations about a partially completed L R C circuit. We're told that it is constructed with an induct er that has an inductive of 0. Hertz and a capacitor with capacitance of two micro fare adds. And we are tasked with determining what the angular frequency is before we finish off the L R C circuit with a resistor. Well, before the resistor is introduced, we can really just find the angular frequency of an L C circuit and treat the system as an L C circuit. The formula for this of course is just one divided by the square root of our conductance times are capacitance. Let's go ahead and plug in our values here. We have one times the square root of 0.4 times our capacities which is to micro fare adds, but we need this in far out. So this is two times 10 to the negative six multiplying straight across. We get 1.12 times 10 to the third radiance per second, which corresponds to our final answer. Choice of C. Thank you all so much for watching. Hope this video helped we will see you all in the next one.
