For the circuit shown in Figure, find, using the superposition theorem,
(a) The current flowing in and the p.d. across the resistor,
(b) The current in the 8V battery and
(c) The current in the 3V battery.
A diffraction grating used at normal incidence provides a spectral line of certain order with wavelength 6000A 0 superimpose on another spectral line of wave length 5000A 0 of th
Necessity Of A Starter For D.C Motors When motor is at rest, then N=0 and due to Eb is directly proportional to N, so At begin E b = zero Thus armature current at t
show that in a glass prism that the refractive index n = sin1/2(A+Dmin)/sin1/2A where a = refracting angle. hence if the angle of incidence i on oan air boundary is 60degrees. calc
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
