    Inductor values and inductor cores.

    Dear nguyennam, The inductance L is normally constant whether in dc or ac circuits. However, in ac circuits, the inductive reactance of the inductor L is equivalent to ωL while ω=2Πf. Hence, the indcutive reactance is dependent on f. Thanks nguyennam. El-Hadidy

    high efficiency InGaN based quantum well solar cell

    wikipedia search for drifts and diffusion current I suppose the best way is to search the internet for animations like the one bbgil has sent. Or use wikipedia or Encarta encyclopedia where simple and straight forward information is introduced. Thank you bbgil for this link. El-Hadidy

    How to use a variable produced using push button in GUI in the workspace?

    Re: Hello Hello, This was the original message: Hello, Using the push button in GUI it is possible to make a variable like y to be equal to 5. The problem is that the variable y is not shown or saved in the workspace. How to make it available in the workspace? Thank you El-Hadidy...

    Power Consumption? Or Current Consumption?

    Hello Eric, The consumption used is always the "Power Consumption". Practically there is nothing called "current consumption". The current is normally dependent on the impedance of your circuit. So, when you have a 15V, 2A supply, the voltage will be constant(15V) but the current will depend...

    Info about the basic digital element - transistor

    Hello Osman, The basic element that is used in most or all digital circuits like AND, OR, NAND,...etc is the transistor. As you already know digital is one/zero or 1/0. A transistor used as an on/off device can accomplish this job (1/0). You can search google for further information where you...
