Q. No.The following table is for which logic gate?
| Input | Output | |
| A | B | C |
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
1. AND
2. OR
3. NAND
4. NOT
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. P-N Junction
2. Transistor
3. Zener diode
4. Triode
The cause of potential barrier in a P-N junction diode is:
| 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:
| 1. |
|
|||||||||||||||
| 2. |
|
|||||||||||||||
| 3. |
|
|||||||||||||||
| 4. | None of the above |
Zener diode is used as:
1. Half-wave rectifier
2. Full-wave rectifier
3. A.C. voltage stabilizer
4. D.C. voltage stabilizer
The depletion layer has (for an unbiased \(p-n\) junction):
1. electrons
2. holes
3. static ions
4. neutral atoms
