List I (Circuit) | List II (Characteristics) | ||
---|---|---|---|
A. | Darlington pair | 1. | uses pnp and npn transistors used as power amplifier |
B. | CB amplifier | 2. | Voltage gain nearly 1 and high input impedance |
C. | Cascade amplifier | 3. | low input impedance used for high frequency isolation |
Reason (R): The existence of magnetic domains is evident from the Bitter powder patterns.
