Match the LIST-I with LIST-II
LIST-I (Configuration of Bipolar Transistors) | LIST-II (Characteristics) | ||
---|---|---|---|
A. | Common Base | I. | Current Gain but no Voltage Gain |
B. | Common Emitter | III. | Both Current and Voltage Gain |
C. | Common Collector | II. | Voltage Gain but no Current Gain |
Choose the correct answer from the options given below:
A battery of emf \( E \) and internal resistance \( r \) is connected to a rheostat. When a current of 2A is drawn from the battery, the potential difference across the rheostat is 5V. The potential difference becomes 4V when a current of 4A is drawn from the battery. Calculate the value of \( E \) and \( r \).
