    Question regarding parallel plate capacitor

    Ok. I think I got the logic here. The field lines of positive plate end on one side of the middle plate(the one facing the positive plate) and the field lines again start from other side of the middle plate and end on the negative plate of the original capacitor. Am I right?

    Question regarding parallel plate capacitor

    If so what is the charge on the middle plate assuming that the middle plate is equally spaced from the other two plates?

    Question regarding parallel plate capacitor

    Lets assume that there is a parallel plate capacitor connected across a supply of V volts. Then, there is charge redistribution between the plates such that finally the potential of positive plate wrt the negative plate is V volts. Let us assume air is the dielectric between the two plates. Now...

    Not getting proper gain in opamp LM324N

    What are rail to rail ICs. I tried to find out on the internet but didn't find a satisfactory explanation. Can anyone explain the exact meaning of rail to rail...

    Need help in electrical load studies

    Hello guys. I study in an engineering college and I'm an electrical engineer. Me and 7 other people have been assigned by our department HOD to conduct load studies of the entire college, each department being individually surveyed. We need to conduct the load consumption of each department at...

    Not getting proper gain in opamp LM324N

    I did the experiment on a trainer kit and rigged up the circuit using patch cords. Is there a chance that I'm not getting proper gain because of noise picked up by the cords?

    Not getting proper gain in opamp LM324N

    LM324 has compatibility for split supplies and single supply. I used split supplies +12V and -12 V. Yeah I forgot to mention that I wasn't getting the output with +5V and ground. I'm sorry but I'm very new to op-amps. I left all pins of op-amp 4 open. What do you mean by tie off? Am I supposed...

    Not getting proper gain in opamp LM324N

    I used this circuit: http://img195.imageshack.us/img195/9979/instamp.jpg I observed the output directly across the CRO. So don't have any idea about output driving impedance...

    Not getting proper gain in opamp LM324N

    I used LM324N(4 opamps on 1 chip) from ON semiconductor to build an Instrumentation Amplifier circuit. I chose the values of the resistors so as to give a gain of 640. But when i checked the gain on the CRO the gain was around 175. What problem could this be? Datasheet...
