    maximum power transfer

    Yes Bob but I read between the lines as I think I know what he meant.

    Meat Balls

    Made some meat balls for tea tonight, very nice. Although the misses said my balls were quite small but nice and tender. Does anyone know a formulla for bigger balls? Am I squeezing them too much? I was thinking RMS root meat squared but not sure. Is it the squeeze ratio to meat quantity. Com on...

    maximum power transfer

    For optimum power transfer to a load you have to match the source resistance with the load resistance this is 50% power. If you change the load resistance up or down this reduces the power in the load and either increase it or decrease the power in the source resistance. SqrtRs/ SqrtRL = 1 so Rs...

    Grounding Question

    Good job it was not mains operated and you asked him to ground the metal work for safety reasons. He then connected the wire to zero volts. Get the point now?

    Crystal Balls for sale

    Got an offer on Crystal Balls if your interested. Buy one get one free. Free p+p. Seem to need them to work out what some people are on about. Then they give a two page explanation of what they want after you ask for more details. Being a so called noob doesn't shouldn't stop them explaning...

    current source transformation

    Any circuit containing just resistances can be converted into an equivalent Thevenin resistance. Don't know what you mean in parallel. In your posts you need to give more details. We can't read minds.

    dual amps for crossover??

    So what are you saying you want stereo from two mono channel? This can't be done if you do. All you will have is two mono channels. Adam

    Clarification about spkrs and crossovers

    Yes Laplace your right. The power it can handle goes down, the minus sign indicates a reduction. I should have explained myself better, sorry Adam

    Lab supply

    So does the circuit now work at 16 volts? What is cutting out at 13 volts?. I did notice and I think Kris mentioned it. Before switch on set and reset are both zero, is this a proper condition for the device? Adam

    Clarification about spkrs and crossovers

    The main issue is in the driving of tweeters. If you drive a tweeter below it's lowest frequency then the power it can handle goes down -6dB per octave. If you don't do this then you can damage it. The other more robust speakers bass and mid range are less efficient above and below their...

    newbie question

    The working voltage of the diode you are talking about is the reverse breakdown voltage as already mentioned. The forward voltage drop of a diode is a function of both current and temperature which increases with increased current and reduces with increased junction temperature. Wattage is...

    How Can I Extend The Range Of This Receiver?

    The manufacturer of the device may have already designed the units for the maximum range for the given power output. Considering the very low power consumption being used, adding a 1/4 wave length whip or a 1/2 wave dipole antenna may not improve the system much. You also may have to do some...

    building an audio crossover

    LR, what inductor and resistor? It has all the looks of a high pass Sallen and key filter, probably Butterworth response. Adam

    How to Connect to H Bridge?

    You could also add another transistor to switch the 0V and a brake Mosfet to supply power the 0V side to act as a brake when the 0V Mosfet is off. But you still don't need a full H bridge. Adam

    How to Connect to H Bridge?

    I think what Bob means is it does not go backward so you don't need to reverse the current to the motors. Adam
