How is the mutual inductance of a pair of coils affected when?
(i) Separation among the coils is enhanced?
(ii) The number of turns of each coil is enhanced?
(iii) A thin iron sheet is placed between the two coils, other factors remaining the same?
Describe your answer in each case.
Give a mathematical expression for linear width of principal maxima in case of single slit Fraunhofer diffraction.
Ohm's law (G. Ohm; 1827): The ratio of the potential difference among the ends of a conductor to the current passing through it is constant; the constant of proportionality is
Curie-Weiss law (P. Curie, P.-E. Weiss) A more general shape of Curie's law, that states that the susceptibility, khi, of an paramagnetic substance is associated to its thermo
Q. When the negative feedback is practical to an amplifier of gain 50 the gain falls to 25. Compute the feedback ratio? Af = A / 1 + Aβ 25 = 50 / 1 + 50 β 1 = 2 / 1 + 50
