    Alternative power supplies and voltages

    I've been poking around power supplies for a while and have been seeing what I can get for amperages. A lot of higher torque DC motors pull a LOT of amps for 12V models (60A stall for the ones I've found new so far, but they also top out at over 20000rpm, too), and I think "low cost gearbox" is...

    Input and Output impedance

    In case of transistor if the input impedance is low it will cause 'loading of circuit' and if output impedance is low it helps to 'drive the load' What is meant by that? ______________ cooking games texas investment properties
