For a p-type semiconductor, the relation between the number density ' $\mathrm{n}_{\mathrm{h}}$ ' and ' $\mathrm{n}_{\mathrm{e}}$ ' is
$\mathrm{n}_{\mathrm{e}}=\mathrm{n}_{\mathrm{h}}$
$n_h \gg n_e$
$\mathrm{n}_{\mathrm{h}} \ll \mathrm{n}_{\mathrm{e}}$
$\mathrm{n}_{\mathrm{h}}=\mathrm{n}_{\mathrm{e}}=0$
If 80 J of work is required in moving an electric charge of ' 2 C ' from a point where potential is " -8 V ' to another point where potential is ' $V$ ' volt, the value of ' $V$ ' is
8 V
16 V
32 V
40 V
A rod of circular cross-sectional area A and length $L$ is wound uniformly with $n$ turns of an insulated wire. If current flowing through the windings is I, the total magnetic flux produced inside windings is $\phi$. The relative permeability of the rod is ( $\mathrm{N}=$ number of turns per unit length) $\left(\mu_0=\right.$ permeability of vacuum $)$
$\frac{\phi \mathrm{L}}{\mu_0 \mathrm{NIA}}$
$\frac{\phi}{\mu_0 \text { INAL }}$
$\frac{\mu_0 \mathrm{IAN}}{\phi \mathrm{L}}$
$\frac{\mu_0 \mathrm{NA}}{\phi \mathrm{LI}}$
