Lc Definition and 167 Threads

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 +...

Homework Statement I need to design a series-tuned LC circuit with a resonant frequency of 2 kHz and and a 2 mH inductor. I need to know what size capacitor I would need? Homework Equations 2 kHz * 1000 = 2000 Hertz 2 mH / 1000 = 0.002 Henry The Attempt at a Solution

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...

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...

Hey all, I'm trying to brainstorm a way to get a sound resonator (the order of hundreds of Hz) to create a voltage. I'm not exactly sure what the resonator should be constructed of... any ideas?

Can we ...! Hello all I want to ask you immportant question ... Can we get High value of LC . i mean A x 10^(-45) and if we get it where we can use it ? i mean type of circute . thank you so much

I know quantum mechanics describies a hydrogen atom in great detail. I'm wondering if there exists another model using the concepts of inductance and capacitance. Obvioulsy there could exist a capacitance between a proton and an electron and inductance of the electron in the electron cloud...

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...

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...

Hi, I was just wondering if someone could point in the right direction to find formulas to calculate the natural resonant frequency of an LC oscillator circuit that uses and air core coil rather than a metal one. Thanks :-)

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...

A fixed inductance 0.66 \mu H is used in series with a variable capacitor in the tuning section of a radio. What capacitance tunes the circuit into the signal from a station broadcasting at 8.11 MHz? Answer in units of pF. I used the equation \omega = 1/ \sqrt LC Solving for C gave me...

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...

LC oscillator - is it quantised? If yes and the oscillation is maintained by a transistor then what is the transistor amplifying?

A square wave pulse (generated using an oscilloscope) is used to induce damped oscillations in a circuit that consits of an inductance L and a capacitance C connected in series. A resistance is present even though no resistor is present in the circuit. a) Find the differential equation for...

Consider a resonant LC circuit. It consists of a capacitor of capacitance 100pf and an inductance of 0.1mH. suppose that when the circuit oscillates the max. voltage on the capacitor is 1mV. Energy stored in the capacitor is given as 0.5CV^2. a) Show that in this circuit one can obtain a...

An oscillating LC circuit consisting of a 7.5 nF capacitor and a 4.4 mH coil has a maximum voltage of 2.0 V. What is the maximum current through the circuit? I got 1.5x10^-8 C for the max. charge.
