    Identify component L2

    Future reference this is the schematic symbol and or designator on a PCB for ferrite bead.

    Identify component L2

    Well then let this be a lesson to you I got to go to bed... sorry buddy someone will be a long shortly. Good night.

    Identify component L2

    While you're making those measurements. I just realized I sound just like my old professor.

    Identify component L2

    Stay with me... concentrate... pay attention... we can find out right now inductors add when put or connected in series Just like resistors they add as well when put in series. Therefore we already know the inductance of L1 add L2 in series with L1 measure the total inductance.

    You're multifunction tester tc1 Apparently this is your inductance meter

    Identify component L2

    Inductors have color codes associated with them like resistors Use this as reference only

    Identify component L2

    Show me your instrumentation you're taking these readings with

    Identify component L2

    Then L2 should have an inductance along with it as wel and vice versa what is the DC resistance of L1

    Identify component L2

    Well put them back! Just kidding what seems to be the problem you are having is it visually L2 looks like a diode and L1 looks like a resistor photos please

    Identify component L2

    Okay just for kicks and giggles un-solder one leg and retest please .

    Identify component L2

    L2 on a PCB silk screened and written on schematic's refers to a component that has inductance, whose value would be in Henry's. That's the fancy way to describe a coil . By the way you see L1 there's nothing there no coil no inductor. For DC inductors will show up as a short circuit this is...

    beginner- Arduino Uno DC motor h-gate problems

    I am not that presumptuous as to speak for the thread starter. It behooves me to adhere too... Empirical evidence is impeachable.

    Low frequency adjustable but stable oscillator

    Uniquely American the Inuit called them qajaq. The Aleut people called them by the name iqyax, while the Yup’ik people called them kayaks. they can traverse the Pacific and Atlantic oceans(coastal areas) as well as inland waterways they come in that slick cedar as well . Don't get me started on...

    Is a circuit necessary in this condition?

    I want to go to your house! I bet you know how to throw a good time.

    Is a circuit necessary in this condition?

    Check your local codes where I'm at Los Angeles electrical outlets in the ceiling are considered a junction box so it complies with code your mileage may vary!

    Is a circuit necessary in this condition?

    The nerve of some people really...I'm glad you said it & not me. My disco lights all have at least a 3-ft cord on it.:p Second answer first you making life hard on yourself can't you install an outlet on the ceiling just plug her in. Same answer. You overthinking it.,0.00025 Ohms? Now I'm...

    The output of IR2104 is not square wave, Ho and Lo are not square wave. When Ho is high, then Lo is also high.

    Welcome to Maker Pro. Thank you for your patience, because there seems to be a very large language barrier and/or translation.

    The output of IR2104 is not square wave, Ho and Lo are not square wave. When Ho is high, then Lo is also high.

    Show a photo of where exactly you're taking your measurements please thank you The scope probes do not look built-in. But then again I've never seen built-in probes

    Altec Lansing BX1121 Pinout

    This seems totally innocent so I believe you have to start your own thread. Include make and model photographs everything you have a link perhaps of the item.

    The output of IR2104 is not square wave, Ho and Lo are not square wave. When Ho is high, then Lo is also high.

    Where are the scope probes that came with the scope? The waveform looks as if the scope probes are not compensated. Question? Are you using alligator clips at that frequency for scope probes.?
