We have recently bought Hart 475 communicator , when we try to use it on transmitter it shows error : Voltage detected on FF connectors and later show No device found , can any one give me and idea about how to solve it.
2766why the frequency and voltage in india is 230v and 50HZ. when compared to USA say 110v and 60 HZ.
1397QUANTUM BIOLOGY - EXAMPLE 33.3 : In quantum biology, microtubule is used to store information in a cell. At temperature of T = 300 K, measured current I in a probe is directly proportional to the supplied voltage V, when passing through a microtubule with resistance R. (a) Form an equation of V as a function of I involving k as a constant. (b) If the microtubule has R = 1 ohm at such condition, find the value of V when I = 2 A. Hint : Ohm's law. (c) Find the relationship of k as a function of R.

How do you size NMOS and PMOS transistors to increase the threshold voltage?
Explain the basic circuits for a current- and voltage- clamp set-up.
What types of I/O have you designed? What were their size? Speed? Configuration? Voltage requirements?
I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
