John Crane Sealing Systems India Quality Engineer Interview Questions and Answers

The count of vernier refers to the number of vernier scales present in a measurement tool.

• Vernier calipers typically have one vernier scale for measuring length.

• Micrometers may have multiple vernier scales for different units of measurement.

• Counting the number of vernier scales can help determine the precision of the measurement tool.

A resistor is an electronic component that resists the flow of electrical current.

• Resistors are used to control the amount of current flowing in a circuit.

• They are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.

• Resistors dissipate energy in the form of heat when current flows through them.

• Common types of resistors include carbon film, metal film, and wirewound resistors.

A transistor is a semiconductor device used to amplify or switch electronic signals.

• Transistors are fundamental building blocks of modern electronic devices.

• They can amplify electrical signals, control the flow of current, and act as switches.

• Common types of transistors include bipolar junction transistors (BJTs) and field-effect transistors (FETs).
