As per the given circuit, the value of current through the battery will be $\dots \; A$.

Consider a circuit consisting of a capacitor $(20 \mu\text{F})$, a resistor $(100 \Omega)$, and two identical diodes connected in anti-parallel as shown in the figure. The resistance of each diode under forward biasing condition is $10 \Omega$. The time constant of the circuit is $\alpha \times 10^{-3} \text{ s}$. The value of $\alpha$ is . . . . . . .

In the circuit shown for the given input voltage $V_i$, the maximum output voltage $V_0$ is

The voltage-current characteristic of a diode during forward bias is given by $I = 7.8 \times 10^{-5} e^{6.5 V_D}$, where $I$ is the current in $mA$ and $V_D$ is the diode voltage in $V$. Find the dynamic resistance of the diode in $\Omega$, when the current is $4 \ mA$.

In the case of forward biasing of a $p-n$ junction diode,which one of the following figures correctly depicts the direction of conventional current (indicated by an arrow mark)?

When a semiconducting device is connected in series with a battery and a resistance, a current is found to flow in the circuit. If, however, the polarity of the battery is reversed, practically no current flows in the circuit. The device may be
