MCQ
The lead marked with the arrow is the $........$
  • A
    collector
  • B
    base
  • emitter
  • D
    core

Answer

Correct option: C.
emitter

It is a $p-n-p,$ transistor. The Lead marked with the arrow is the emitter. It tells the direction of the flow of the holes i.e, the flow of conventional current.

Two wires each carrying a steady current $I$ are shown in four configurations in Column $I$. Some of the resulting effects are described in Column $II$. Match the statements in Column $I$ with the statements in Column $II$ and indicate your answer by darkening appropriate bubbles in the $4 \times 4$ matrix given in the $ORS$.

Column $I$ Column $II$
$(A)$ Point $P$ is situated midway between the wires. $Image$ $(p)$ The magnetic fields $(B)$ at $P$ due to the currents in the wires are in the same direction.
$(B)$ Point $P$ is situated at the mid-point of the line joining the centers of the circular wires, which have same radii. $Image$ $(q)$ The magnetic fields $(B)$ at $P$ due to the currents in the wires are in opposite directions.
$(C)$ Point $P$ is situated at the mid-point of the line joining the centers of the circular wires, which have same radii. $Image$ $(r)$ There is no magnetic field at $P$.
$(D)$ Point $P$ is situated at the common center of the wires. $Image$ $(s)$ The wires repel each other.
