Question

i N1 N2

Applying a DC current of sufficient magnitude to Coil 1 will sustain a glowing light bulb connected in Coil 2.

True False

Answer 1

Given circuit of transformer NI N2 solution we is a Static 00 Basically Krow transformer device which Works the principle of mutual indeechion which States that enf elecho notive force indice pate change of magnetic magnetic field that is e Νεφ toil) 14 ماهینا in a Coil if of occurs Centiin or we can write as es Nad di It de L volls de CS Scanned with CamScanner

con So from the above relation that rate of change of is necessary so to that generale coil. enf un genaralised current we are But here applying DC Currect which is Constant in nakere hence rate is not of change of current possible in Cose DC henu will emp in the induced Secondary col therefore glowing of ligne will not sustain Currect of + न of time too OCT Note: conider smell fraction sudden say impulse well for a fraction of moment so for fraction of moment wiu Light Meet glow the is infulse large that it may luern the Hence glowing of bulb light not Sustain sustain windings well for long Hence the answer is false.
