In a circuit containing diode , say in forward bias , the positive and negative terminals are connected with the diode , keeping what in mind ? Please tell for reverse bias also .

Question

anonymous · Answer

do you kno what a forward bias is supposed to do?!

anonymous · Answer

firstly , thanks a lot ......yes , it is supposed to decrease the pot barrier , increase the curent ....

anonymous · Answer

ok.. if u want that to happen
which terminals do you think you have to connect the P side and N side to?

anonymous · Answer

i know ...that with the battery p side goes to the positive terminal in fwd bias
....but my tchr while teaching it had told , that you have to specifically connect the positive terminal of the ammeter and voltmeter somewhere which i can't recall..and 
.behind which the logic i don't know..

anonymous · Answer

oh.. 

the voltmeter and ammeter connections are always the same regardless of which circuit you are dealing with 

+ve of the batter goes to the +ve of the ammeter, and the voltmeter..

ammeter always in series, voltmeter always in parallel.. 

so this IS ALWAYS TRUE.. regardless of what circuit you are building!

anonymous · Answer

Oh ! But why so ? The only difference will be the deflection will be in the opp side !

anonymous · Answer

you are absolutely right
but have you seen an ammeter?
its not ALLOWED to deflect on the opposite side.. so 
a) u ll not measure anything.. and b)  u may even spoil it!

anonymous · Answer

but then why do the evn build it like dat if i cant measure on one half side of it ?
