Q1. Capacitor and voltage in series and parallel
Ans. 
Capacitors in series add reciprocally, in parallel add directly. Voltage in series is the sum, in parallel is the same.
• Capacitors in series: 1/Ctotal = 1/C1 + 1/C2

• Capacitors in parallel: Ctotal = C1 + C2

• Voltage in series: Vtotal = V1 + V2

• Voltage in parallel: Vtotal = V1 = V2

Q1. Analyse the output of the circuitry
Ans. 
The output of the circuitry needs to be analyzed for functionality and accuracy.
• Examine the input and output signals to ensure they are within expected ranges

• Check for any noise or interference in the output

• Verify that the circuit is functioning as designed based on the specifications

• Look for any potential issues or errors in the output

Q1. Explain CMOS inverter?
Ans. 
CMOS inverter is a type of digital logic gate that implements logical NOT operation.
• CMOS inverter consists of a PMOS transistor connected in series with an NMOS transistor.

• When input is high, PMOS conducts and NMOS is off, output is low.

• When input is low, NMOS conducts and PMOS is off, output is high.

• CMOS inverters are widely used in digital circuits for logic operations.

• Example: Inverter gate in a CMOS technology-base

Q1. Difference between sanity and smoke
Ans. 
Sanity testing is a narrow and deep testing approach to check if the specific functionality is working fine after changes, while smoke testing is a broad and shallow testing approach to check if the software build is stable enough for further testing.
• Sanity testing focuses on specific functionality, smoke testing checks overall stability

• Sanity testing is usually performed after a specific change, smoke testing is perfo...read more

Q2. Difference between regression n retesting
Ans. 
Regression testing is testing the entire application after changes, while retesting is testing specific areas after fixes.
• Regression testing is done to ensure that new code changes do not affect existing functionality.

• Retesting is done to verify that a specific bug or issue has been fixed.

• Regression testing involves running the entire test suite, while retesting focuses on specific test cases.

• Example: After fixing a bu...read more

Q3. Find repetitive words in string program
Ans. 
Program to find repetitive words in a string
• Split the string into words using a delimiter like space

• Create a hashmap to store word frequencies

• Iterate through the words and update the hashmap

• Identify words with frequency greater than 1 as repetitive
