Punjab Chemicals & Crop Protection Interview Questions and Answers

Q1. One input put is High than output will be high which gate?
Ans. 
The gate is an OR gate.
• An OR gate produces a high output if any of its inputs are high.

• It follows the logic of 'if A or B or C is high, then the output is high'.

• Examples of OR gates include the 7402 IC and the OR gate symbol in digital circuit diagrams.

Q2. How to use in multimeter in digital circuits to measure?
Ans. 
A multimeter can be used in digital circuits to measure voltage, current, and resistance.
• Set the multimeter to the appropriate mode (voltage, current, or resistance)

• Connect the multimeter probes to the circuit

• Read the measurement value on the multimeter display

• Example: To measure voltage, set the multimeter to voltage mode, connect the probes across the component or circuit, and read the voltage value on the display

Q3. One input is complicate than output will high which gate?
Ans. 
The gate that has a more complex input than output is the NAND gate.
• NAND gate has an output that is high only when both inputs are low.

• It is considered more complex because it combines the functions of an AND gate and a NOT gate.

• Other gates like AND, OR, and XOR have simpler input-output relationships.

Q4. The high currents will be flow in___?
Ans. 
High currents will flow in conductive materials.
• High currents flow through materials with low resistance.

• Conductive materials such as metals allow high currents to pass through them.

• Examples of conductive materials include copper, aluminum, and silver.

• High currents are commonly found in electrical circuits and power transmission systems.

Q5. How to connect ammeter in circuits
Ans. 
An ammeter is connected in series with the circuit to measure the current flowing through it.
• Connect the positive terminal of the ammeter to the positive terminal of the power source.

• Connect the negative terminal of the ammeter to the load or component where you want to measure the current.

• Ensure that the ammeter is capable of measuring the expected current range to avoid damaging it.

• Avoid connecting the ammeter direct...read more
