Associated Electro Chemical Interview Questions, Process, and Tips

1 cm = 10 mm

• 1 cm is equal to 10 mm

• To convert cm to mm, multiply the value in cm by 10

• For example, 5 cm is equal to 50 mm (5 cm x 10 = 50 mm)

Specific gravity is the ratio of the density of a substance to the density of a reference substance.

• Specific gravity is a unitless measurement that compares the density of a substance to the density of a reference substance (usually water).

• It is commonly used in chemistry to determine the purity of a substance or to identify an unknown substance.

• The specific gravity of water is 1.0, so substances with a specific gravit...read more

The unit of resistance is Ohm (Ω)

• The unit of resistance is named after German physicist Georg Simon Ohm

• Resistance is measured in Ohms (Ω)

• Common examples of resistance include resistors in electronic circuits

Resistance is measured using a multimeter by applying a known voltage and measuring the resulting current.

• Use a multimeter to measure resistance

• Set the multimeter to the resistance (ohms) setting

• Connect the probes to the material or component being tested

• Apply a known voltage and measure the resulting current

• Calculate resistance using Ohm's Law: R = V/I

Percentage can be found by dividing the part by the whole and multiplying by 100.

• To find percentage, divide the part by the whole and multiply by 100.

• For example, to find 20% of 50, calculate (20/100) * 50 = 10.

The 7QC tools of quality are essential techniques used in quality control to identify and solve problems.

• Check sheets: Used to collect and organize data, such as defect counts

• Pareto charts: Helps prioritize issues by showing the most significant factors

• Cause-and-effect diagrams: Identifies root causes of problems

• Histograms: Displays data distribution

• Scatter diagrams: Shows relationship between two variables

• Control char...read more

I worked at XYZ Company as a Quality Engineer for 3 years.

• Implemented quality control processes to improve product reliability

• Conducted root cause analysis for non-conformances

• Collaborated with cross-functional teams to address quality issues
