One part of a device is connected to the negative terminal of a battery and the other part is connected to the positive terminal of a battery. If their ends are now altered, current does not flow in circuit. The device is:
1. \(\mathrm{p\text-n}\) Junction
2. Transistor
3. Zener diode
4. Triode
| 1. | Concentration of positive and negative ions near the junction. |
| 2. | Concentration of positive charges near the junction. |
| 3. | Depletion of negative charges near the junction. |
| 4. | Increment in concentration of holes and electrons near the junction. |
The truth table for the following network is:
