Electrical Research & Development Association Quality Engineer Interview Questions and Answers

Tolerance refers to the acceptable range of variation in a measurement or specification.

• Tolerance is the allowable deviation from a desired value or specification.

• It is used to determine if a product or process meets the required standards.

• Tolerance can be expressed as a numerical value or a percentage.

• For example, if a measurement has a tolerance of ±0.1mm, it means that the actual value can vary by up to 0.1mm from t...read more

RAM stands for Random Access Memory.

• RAM is a type of computer memory that can be accessed randomly.

• It is used to store data that is currently being used by the computer's operating system, applications, and processes.

• RAM is volatile memory, meaning its contents are lost when the computer is powered off or restarted.

• It is much faster than other types of storage like hard drives or solid-state drives.

• RAM capacity affects...read more

UPS stands for Uninterruptible Power Supply.

• UPS is a device that provides emergency power to a load when the input power source fails.

• It ensures that critical equipment remains operational during power outages.

• UPS systems can be used for various applications, including protecting computers, servers, and other electronic devices.

• They typically consist of a battery, an inverter, and a charger.

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.

• Ohm's Law is named after the German physicist Georg Simon Ohm.

• It is commonly represented by the equation: V = I * R, where V is voltage, I is current, and R is resistance.

• This law helps in understanding the relationship between voltage, current, and resista...read more
