### The Intuition for RLC circuits

Resistors are the electrical equivalent of friction and produce losses to remove energy from the system. If you drop a frictionless pendulum to swing it, how long does it take to settle? Infinite time,...

### LC Circuit problem!

200 V is indeed the correct answer, assuming ideal components. Think about this in the time domain. When the switch is initially closed, all the 100 V of the battery is applied across the inductor. ...

### Measure temperature on a moving engine valve: transfer voltage and reading wireless?

A good way might be to use a pyrometer. It is an optical device that receives the heat/light emitted by the object whose temperature needs to be measured and then uses part of that "spectra" to ...

### Why is series LC circuit not behaving as band pass filter?

That's the problem with simulating with "ideal" components — you see behaviors that you would never see in the real world. Your circuit has no resistance in it anywhere. The function generator ...

### Thevenin Equivalent Voltage: why ignore the 3-kΩ resistor?

The Thevenin voltage is when the output terminals are open-circuit so any series resistance (3K in this case) has no effect. We can also ignore the 4K resistor since it's in series with a current ...

### Inductor and capacitor for energy storage instead of battery

...use a LC network to store small amount of electrical energy (500 mWHr or less) You might think that 0.5 WHr is "small" but for an LC tank, it is HUGE. So what is 0.5 WHr? 0.5 Watt = 0.5 Joule / ...
