In a $p-n$ junction diode,the direction of diffusion current is from

In the given figure,each diode has a forward bias resistance of $30\, \Omega$ and infinite resistance in reverse bias. The current ${I}_{1}$ will be $....\,A$.

In a $p-n$ junction diode, an electric field of magnitude $2 \times 10^5 \ V/m$ exists in the depletion region. $A$ particle with charge $-3e$ can diffuse from $n$-side to $p$-side, if it has a minimum kinetic energy of $0.6 \ eV$. The width of the depletion region of the $p-n$ junction is: (in $nm$)

If a $p-n$ junction diode is forward biased,then:

In the given circuit, the current through the battery is ...... $A$.

In the circuit shown in the figure,determine the voltage $V_0$ for the circuit network.
