# Questions tagged [inductance]

The property of an electrical conductor through which a change in current through it induces an electromotive force in both the conductor itself as well as in any nearby conductors by mutual inductance. Also use more broadly for electromagnetic phenomena in solenoids.

### An RLC series circuit with current equal to one half the resonant current [closed]

Consider a RLC circuit coupled in series supplied by the AC voltage v= 30 sin(w t), R=50 W, L= 600 mH, frequency f=5 kH. The inductor is a solenoid and the capacitor has cylindric configuration. The ...

### How can this circuit be simplified in the first moments after the circuit breaker closes?

The book states that in this circuit after the transient the branch with the capacitor can be ignored while the branch with the inductance can be considered constituted only by a resistance. This ...

### Good braking system for a mini car that can be triggered by a beam above the car that it will go past

I want to create a braking system for a mini car (essentially an aluminium body around 30cm long with 2 sets of axles with wheels (laser cut circles) connected to the end of each axle on the front and ...

### Work done by battery [closed]

In charging a capacitor to a charge $Q$ Is there an equivalent to this in setting up current through an inductive circuit? Energy stored in inductor $= 1/2Li^2$ What would be the work done in setting ...

### Current in primary circuit when diode in secondary circuit is reverse biased

Let's say we have an ideal transformer with a diode in the secondary circuit: If the diode is reverse biased, there would be no current in the secondary circuit, which would mean that there is no ...

### LC circuit in spring system

We have a setup of a metal spring with a mass. This would oscillate nicely. Additionally, an inductor with a capacitor also oscillates nicely. If we were to combine these two setups, where the mass is ...

### Why is the relation between voltage ratio and frequency a linear one in a lumped transition line?

In an experiment the cutoff frequency of a lumped transmission line is determined by measursing the ratio of the output/input voltages. The lumped transmission line is a ladder network of 40 ...

### Why does current lag behind voltage in an inductor in AC Circuit?

In a simple AC circuit with a source and an inductor, we have $$\Delta V + \Delta V_{L} = 0$$ due to KVL where $\Delta V$ is the voltage source and $\Delta V _{L}$ is the voltage across the inductor....

### Question about the impedance of a RLC circuit

I made an experiment with a RLC circuit, and I found the resistance, the capacitance, and the inductance with measures. So I decided to calculate the impedance of the circuit, depending on the ...

### An *actual*, relativistic, intuitive explanation for inductance…?

I searched high and low, and as far as I can tell, after years, there is not a single video or site that actually explains inductance in an intuitive way. I mean an actual explanation. Not “Faraday’s ...
