Q3. Explain ohm law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
• Ohm's Law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current flowing through a circuit when the voltage and resistance are known.

• It also helps in determining the resistance in a circuit...read more

Q1. What is lpad and rpad?
Ans. 
lpad and rpad are functions used in SQL to add padding characters to the left or right of a string.
• lpad adds padding characters to the left of a string

• rpad adds padding characters to the right of a string

• Syntax: lpad(string, length, padding_character)

• Example: lpad('123', 5, '0') will result in '00123'

• Syntax: rpad(string, length, padding_character)

• Example: rpad('123', 5, '0') will result in '12300'
