    What is an electric field?

    What is an electric field? Is it matter?Does it have mass? If no then how does it store energy in a capacitor?Since to store energy,there must be prescence of matter. e.g: If I lift a block of metal,energy is transffered from one matter(namely me)to another matter(namely block)and the block...

    Von neumann vs Harvard architectures

    HI All, What is the difference between Von neumann architecture & harvard architecture? Is it that von neumann has unique address space where all the instructions,data & peripherals are mapped whereas,harvard has seperate address spaces for instructions & (data + peripherals).WHat...

    basics of electrical supply

    I think my basic question remains unanswered as far as theory goes: "But,if neutral is not connected to ground,and there is no special protection circuits around,is it that we never will get shocked when we hold a live wire? "

    basics of electrical supply

    Hi All, I wanted to know that is neutral wire connected to earth at some point ? If not then how do we get shocked,since to get shocked,current must flow from live to neutral? -Shekhar

    Beta of the BJT

    Hi AudioGuru, If I select the above transistor and if the Ic -Vce 'test conditions' don't exist in my circuit i.e I have my own Ic Vce depending on my curcuit conditions then what beta should I consider? Thanks, -Shekhar

    read/write operations

    what is the advantage of reading if one is going to modify i t? Is it that the value is read,compared to the one selected for modification then if they are same,the value is not rewritten.if there is a mismatch,then the new value is written? -Shekhar

    FM WAVE PROPAGATION

    Hi Everyone, Does LOS mean that the t'mitter and the r'ver should see each other? what if I want to send a signal a few stories up/down my building?In that case how will the x'mission be, considering omnidirectional antennas? -Shekhar

    read/write operations

    Hi All, I wanted to know what is meant by a read-modify-write operation?how is it different from a normal read/write operation? Another ques: What is a tri-state?what is the voltage on tri-stated pins? Thanx -Shekhar

    X'tors and their symmetry

    Hi All, Why is X'tor not a symmetrical device i.e if c-b is forward biased & b-e is reverse biased will it function the same and give same characteristics? I heard that FET's are symmetrical when used as switches.Is it true? rgds, -Shekhar
