In the given circuit,the current $(I)$ through the battery will be $..........\,A$.

Consider the following circuit. The waveform given in input is as shown. If ${V_{B_1}}$ and ${V_{B_2}}$ are less than the peak value of the input,then the output will look like:

Find the current $i$ in the circuit shown.

In a forward-biased $P-N$ junction diode,how does the potential barrier behave?

An electron in the $n$-region of a $p-n$ junction moves towards the junction with a speed of $5 \times 10^5 \ m/s$. If the barrier potential of the junction is $0.45 \ V$, then the speed with which the electron enters the $p$-region after penetration through the barrier is (Charge of the electron $e = 1.6 \times 10^{-19} \ C$ and mass of the electron $m = 9 \times 10^{-31} \ kg$).

Currents flowing in each of the following circuits $A$ and $B$ respectively are
