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 ...read more

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.
