    Electrical Solar panel thickness to avoid breaking DIY

    Hello I am currently building DIY solar panel.I have a problem regarding the build up of the panel. My question is can I attach the cells on to a normal transperant glass of about 5mm thick by a transperant silicon? My concern is if the cell will break or not, by the outer environment ...

    Uninterrupted Power Supply (UPS)

    Hi, I have an ups used for my PC. I have just replaced his faulty battery and checked the output on battery operation with a multimeter.The reading are as follows: 1. Without load the ouput is about 184V. 2. With load the output is between 196V to206V. Can someone tell me if I use the ups...

    Is Common Mode When Identical Signals Are Applied to a Differential Amplifier?

    I have the following situation. An opamp is used to filter 50 hz supply from a patient to read a perfect ecg. Attached you can find the opamp configuration. The AC interference is connected to the opamp in the inverting input and non inverting as common mode and an ecg signal is applied...

    Deriving a Logarithmic Amplifier: V=ClnI

    Thank you for your replay the final answer is I think VolnVin-C=Vout Might the equation be KlnVin=Vout or VolnVin=Vout for a particular R I think? In other words Voln(RIs)~0 Thank you for your help!

    Deriving a Logarithmic Amplifier: V=ClnI

    I tried follow the above steps by Redbelly,please tell if I did wrong or not given I=Ise^Vout/Vo I made Vout subject of the formula gives Vo(lnI-lnIs)=Vout using Ohms Law did I in terms of V and R Vo(lnVin/R-lnIs)=Vout Vo(lnVin-lnRIs)=Vout VolnVin-VolnRIs=V (I think that...

    Deriving a Logarithmic Amplifier: V=ClnI

    First thanks for your replay I understood your first point that R (input resistance) is included in K but I can't understand is how R is included in K.In the previous post by Phark showed that Vout=-ClnVin+ClnR is not equal to KlnVin.Can you state the steps how you concluded that? Sorry...

    Deriving a Logarithmic Amplifier: V=ClnI

    I tried to think about it given V=clnI make I subject of the formula gives I=e^v/c but I can't go any further unfortunately.
