explanation of duality theory ? relativity phenomenon is largely based on the duality principle . the davisson and germer experiment proved the wave nature of electrons . however i wish to understand the cause of it .

hey the n (for the B field is B=μo*i*n where μo is the permeability) you mentioned first time is no. of turns per unit length the n you mentioned the second time is no. of turns N n=N/L L- length of the solenoid As to the basic question , what you are trying to do is impossible...

i doubt your induction theory . because if the induction is due to the ac supply then the led should be ON and OFF very rapidly . it should not glow continuously (@reverse bias of a diode ). of course that blink might not be tangible but its still a thought ... i can not explain the capacitor...

i think your anwer is correct

s=(Ig/(I-Ig))*R s-required shunt R-resistance of galvanometer(50) Ig-full scale deflection current of the galvanometer(0.1) I-desired current range(60) just substitute the given data

is the answer 0.083ohm

can the range of an ammeter be decreased ? @Delphi51 in the above comment you said that we don't need ammeter of a particular range . i comprehend that as by connecting a shunt the range can be increased . but for a given purticular ammeter is there any way that the range might be decreased ...
