Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFInput Terminal Emitter–Base (EB)
Output Terminal Collector–Base (CB)
Input voltage: VEB
Output current: IC
Since for Amplification Application in BJT
EB Junction → Forward Biased (Low Impedance)
CB Junction → Reversed Biased (High Impedance)
