COMEDK · Physics · 30. Semiconductors
Choose the correct statement.
- A A \(p\)-type semiconductor is positively charge(d)
- B The Boolean expression \(1 \cdot 0=0\).
- C The majority carrier in \(n\)-type semiconductor is hole.
- D A transistor cannot be used as a switch.
Answer & Solution
Correct Answer
(B) The Boolean expression \(1 \cdot 0=0\).
Step-by-step Solution
Detailed explanation
As per Boolean postulates, \[ \begin{aligned} 1 \cdot A &=A \\ \Rightarrow \quad 1 \cdot 1=1 \text { and } 1 \cdot 0 &=0 \end{aligned} \] \(p\)-type semiconductor is electrically neutral. The majority charge carriers in \(n\)-type semiconductor are electrons. A transistor can be…
