    What is the voltage across this capacitor, inductor and resistor?

    Yes Yes! ok so now 1/(1/-24.1 + 1/414.7) Xp=-25.6 Therefore current through R is Ir = (270-25.6) = 244.4 That doesn't sound right...

    What is the voltage across this capacitor, inductor and resistor?

    Combined resistance would be using 1/((1/R1)+(1/R2)) which as far as I know works with impedance just like it does resistance. The reactance of L would be (2*pi*f*L) and the reactance of C would be (1/(2*pi*C)) Giving me: R=270 Xc=24.1 Xl=414.7 I could find the impedance of C and L by taking...

    What is the voltage across this capacitor, inductor and resistor?

    Thank you Dave, At risk of sounding well understudied is there a way to solve this with simple algebra? I was under the assumption there would be a variation on the existing equations used to find Z and X in simple RLC circuits which would eventually solve like a literal resistor network...

    What is the voltage across this capacitor, inductor and resistor?

    I can solve for the questions in completely series or parallel circuits however having the capacitor and inductor in parallel while the resistor stays in series is stumping me completely.

    Magnetic field put off by high current (causing cross-talk between wires)

    Ok that makes sence, even if any voltage is generated in my coil harness or injector harness it will be very small and not offer enough current to actually do anything?

    Magnetic field put off by high current (causing cross-talk between wires)

    Ok so I haven't been on here for a while but I can't seem to find an answer to my question anywhere and really need some help! So I not only am an electronics hobbies but I have fun installing car audio systems as well. The problem I am running into is that I would like to run an alt wire...

    MOSFET not working with digital input gate signal, Help please

    So after taking a look at my program i realized it was simpler to do then I thought. So I was able to take my word variable holding the 1024 bits of the pwmduty and before It actually fires I wrote "let w11=1024-w11" and changed w11=0 to w11=1024 wherever the mosfet is supposed to shut off. The...

    MOSFET not working with digital input gate signal, Help please

    Ok! So i went ahead and changed the frequency in my program, picaxe doesn't really list a way to know what frequency you are actually getting out of the 0-255 variable so I took it from 255 down to 50, (I think it is something like 17hz,) and although it did not completely fix the problem as far...

    MOSFET not working with digital input gate signal, Help please

    I will admit I am relatively new to fets and although I have read the datasheet there may be somthing you guys see that I don't. In terms of the frequency, I will definitely try lowering the frequency next chance I get to make up for that gate capacitance and hopfully improve the overheating...

    MOSFET not working with digital input gate signal, Help please

    I didnt get to it today but im still here!

    MOSFET not working with digital input gate signal, Help please

    As for a schematic is there a program that you guys use? I agree it would benefit everyone especially me. I normally just draw mine but this is important to me and ill give you whatever is needed. My scope cant seem to latch onto the frequency but every time i turn it on i can hear almost...

    MOSFET not working with digital input gate signal, Help please

    Ok, so i have a picaxe microcontroller putting out a pwm signal to the gate of an irlb3034 "logic level" n-channel mosfet. The mosfet is for grounding on and off about 8v of 20 to 40 amps. When i take my circuit and jump 8v directly to the gate of my mosfet everything works perfectly...

    ASK transmitters in parallel

    I am in the US and didn't realize there was a law so ill keep bellow 20mw. I really want a somthing plug and play, could I possibly take one f these modules and tap a mosfet amplifier circuit onto the antenna pin and take measurements in order to achieve a true 20mw thus using the module only...

    ASK transmitters in parallel

    I have built a remote control car, pwm speed controll and all, using picaxe microcontrollers and gained a lot of experience doing it. I used a low power i think 20mw transmitter you can find all over ebay that uses a 433hz carrier wave. A long time ago i found a 1w transmitter meant to be a step...

    Equilizer with lm833

    Ok great! Sorry I havnt responded for a while. This all had helped a lot and once i find time to experiment i may have more questions so ill make another thread, see you all later!
