Q1. What's Ohm's 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 of the conductor.
• Current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R): I = V/R

• It is named after German physicist Georg Simon Ohm

• It is commonly used in electrical engineering to calculate current, voltage, and resistance

Q1. How to calculate the weight?
Ans. 
Weight can be calculated by multiplying the mass of an object by the acceleration due to gravity.
• Weight = mass x acceleration due to gravity

• The standard acceleration due to gravity on Earth is 9.81 m/s^2

• For example, the weight of a 10 kg object on Earth would be 10 kg x 9.81 m/s^2 = 98.1 N

Q1. How we calculate the PPM
Ans. 
PPM (Parts Per Million) is calculated by dividing the number of defective units by the total number of units produced, then multiplying by one million.
• Calculate the number of defective units.

• Calculate the total number of units produced.

• Divide the number of defective units by the total number of units produced.

• Multiply the result by one million to get the PPM value.

Q1. What is ppm? And how to calculate?
Ans. 
PPM stands for parts per million, a unit of measurement used to express very small concentrations of substances in a mixture.
• PPM is calculated as (mass of solute / total mass of solution) * 1,000,000

• For example, if a solution contains 5 grams of solute in 10,000 grams of solution, the PPM would be (5 / 10,000) * 1,000,000 = 500 PPM

• PPM is commonly used in various industries such as manufacturing, environmental monitorin

Q2. How to find a least count of vernier caliper
Ans. 
The least count of a vernier caliper can be found by dividing the smallest division on the main scale by the total number of divisions on the vernier scale.
• Divide the smallest division on the main scale by the total number of divisions on the vernier scale

• Example: If the smallest division on the main scale is 0.1 mm and there are 10 divisions on the vernier scale, the least count would be 0.1 mm / 10 = 0.01 mm
