i mean the normal pn diode used in circuits

hey thanks

the electric field produced due to a time varying magnetic field is non-conservative in nature. does it follow gauss law?

what's the diff bw live wire and neutral wire then? after all they are only connecting wires in the circuit

why is fuse connected in the live wire only? as current is same throughout the circuit( it is produced simultaneously in the whole circuit ie it does not 'originate' from any source) putting the fuse anywhere in series with the circuit should work.

when forward bias of led is increased, the intensity of emitted light increases until it reaches a max after which it starts decreasing again...why? also, in which of the two cases is barrier potential greater, led or pn diode?

L di/dt=V( by Kirchoffs law).this would mean current is forever increasing infinitely. is this practically possible?

-------------------------------------------------------------------------------- is it true that when the net force on a rigid body is zero, the torque about any line perpendicular to the plane of the forces is equal? it is known that angular velocity, and hence angular acceleration about...

hey, thanks for the link. but i still have a doubt. for transmission of power, high voltages are used so as to reduce current in the wires. then power dissipation thru resistance would be i^2*R.but it can also be written as v^2/R. so what's the actual difference bwtn power supplied and power...

will there be any current in a circuit with an ideal dc battery and an ideal inductor?

how does a transformer work?

can u suggest a good site for studying young's double slit experiment involving interference of light coming from two coherent sources online?

i found this in a textbook. at a high altitude the temperature of the atmosphere is 500 degrees centigrade. yet an animal there would freeze to death and not boil. why does this happen?

that doesn't answer my question, is there any physical significance of mechanical equivalent of heat?

we define mech equivalent of heat as the amount of work done in joules in order to provide 1 cal of energy. 4.2 J= 1 cal is mech equiv of heat simply a conversion factor or does it have any other physical significance?
