Q. State Moseley's law.
The frequency of the spectral line in the qualities X-ray spectrum is directly proportional to the square of the atomic number (Z) of the element considered.
That is ν α Z2 or ν = a(Z - b)
Whereas a and b are constants depending upon the particular spectral line.
Alternating Current: (AC) Such a current can be obtained if a resistor is linked in series with a source of alternating voltage. This current alters its direction so many times
