    What is Electromagnetic Fields

    This is so simple.This is the combination of electric and magnetic field. let you assume one conductor.you passed the electrical supply through this conductor and outside of this conductor some magnetic field will be created.this is called EMF.

    Capacitor allows which voltage, either DC or AC? and why?

    Capacitor allows which voltage ,either DC or AC? and why? hi, I used the capacitors in my circuit.I only know about capacitors which are stored the electrical energy.But somebody says it allows only AC voltage.Is it true ? Pls Explain in detail.:!::!::!::!::!::!:

    i can't find 24LS256 EEPROM datasheet

    hi everybody ,i need help to find 24LS256 EEPROM datasheet. i already search in google but there is no datasheet in that name.the google only shows 24LC256 IC's datasheet.but i need 24LS256. anybody help me.:?::?::?:

    what is modbus?why we use that protocol?

    i need to write the coding for modbus by using stm controller.but i don't know how to start that. because i have no knowledge about modbus?anyone help me to how i implement the modbus in my controller? and tell the basic things about modbus.

    how to receive the signals via CAN protocol in stm32f407xx microcontrolles

    now i develop the CAN protocol coding by using STM32f407Xg microcontroller. also i done the CAN trnsmission process but i can't understand how to receive the datas using CAN protocol and i don't know where i modify the coding.pls anybody help me about how to receive the CAN data and what are the...

    [Moved] in practically ,why we have to connect limited slave devices in I2c?

    i know in I2c bus we can connect upto 114 different slave devices.but why we cannot connect all slave devices (i.e 2^7 = 128).

    CAN COMMUNICATION:why we use CAN trasceiver ?

    In some controllers CAN protocols are available.but we use the CAN transceiver IC. why?.Pls detail about CAN communication?....

    why we use CAN transeiver in CAN communication?.........

    in on chip CAN protocols are available in some IC's.in that IC's CAN RX and CAN TX pins are available.but why we use the CAN transceiver IC for seperating the datas to CANH and CANL.pls answer detail about CAN communication.
