What is Lc: Definition and 167 Discussions

The Lexus LC (Japanese: レクサス・LC, Rekusasu LC) is a grand tourer manufactured by Lexus, Toyota's luxury division. Based on the 2012 LF-LC Concept, it was revealed at the 2016 North American International Auto Show in Detroit. It replaced the SC, which was produced from 1991 to 2010. It is the first Lexus model to utilize the GA-L platform, which, along with other components, is shared with the full-size XF50 series LS sedan. According to Lexus, the name "LC" stands for "Luxury Coupe".

    LC Circuit: Initial Conditions and Switch

    Hello guys. I have a simple question regarding an LC circuit. Imagine a voltage source V_0, a capacitor C and an inductor L, all hooked up in series. I know that the equation governing the behvior of the system is V_0=\frac{1}{C}q(t)+L\ddot{q}(t), and hence q(t)=A\cos \omega t +...

    LC Oscillations how are they even possible?

    If i connect an inductor and a charged capacitor as the only circuital elements in a circuit [other than lead wires], something called 'LC Oscillations' happen. According to what I've read, due to the charge on the capacitor, there is a potential difference across the ends across which the...

    Solve GRE Problem: LC Circuit Maximum Power Output

    Homework Statement An AC source is connected to an LRC circuit (Inductor is connected to Capacitor in series, and then it is connected to register in series). Energy is stored in the capacitor and inductor and is dissipated in the resistor. At what time is the energy dissipated at the maximum...

    Understanding LC Circuits: Voltage & Current Explained

    It's been a while since i did physics at Uni and I'm a bit rusty with it all but I've recently been trying to get my head around LC circuits i've looked at the wikipedia website and seen the solved differential for LC circuits but I'm a bit confused with the following assumptions...

    Engineering Explain LC Resonance in a Circuit

    Hey guys, I'm doing a lab report on an LC resonant circuit, and it's I've kinda hit a speedbump in trying to explain why exactly the resonance is happening. I don't know if "LC resonant circuit" is a normal thing to call it so i'll explain a bit. You have V_in which goes into a resistor, then...

    Requesting Assistance to Access Paper on Infinite LC Ladder Networks

    I'm interested in understanding the physics of infinite LC ladder networks (not homework or coursework). There's a paper that looks good on the subject in the American Journal of Physics, but I don't have a subscription. Could some kind soul who has an unlimited subscription (so it wouldn't...

    LC Circuit Oscillations: Check My Work and Find Energy and Frequency Details

    I'm not too confident in my work for this problem, so I was wondering if someone could check it over for me. Consider a circuit with 4 elements, C1=100micro farads, C2=50micro farads, L1=20mH, and L2=10mH. At t=0, the capacitors are charged with Q=0.01 Coulomb. There is initially no current...
