Cradle Life Sciences Interview Questions and Answers

The unit of capacitance is the farad (F).

• The unit of capacitance measures the ability of a capacitor to store charge.

• It is named after the English physicist Michael Faraday.

• Common subunits of capacitance include microfarads (μF) and picofarads (pF).

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction.

• They consist of two or more coils of wire, known as windings, which are wound around a common magnetic core.

• The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.

• W...read more

Nuclear power plants have the minimum running cost.

• Nuclear power plants have low fuel costs as they use uranium, which is inexpensive and abundant.

• They require less fuel compared to fossil fuel power plants.

• Nuclear power plants have high initial construction costs but lower operating costs in the long run.

• Renewable energy sources like solar and wind have no fuel costs, but their initial setup costs are higher than nucl...read more

The hydroelectric power plant has the highest area required.

• Hydroelectric power plants require large areas of land for reservoirs and dams.

• The area required for a power plant depends on factors such as the size of the reservoir and the capacity of the plant.

• Other types of power plants like solar or wind may require less land area compared to hydroelectric plants.

• Examples of large hydroelectric power plants include the ...read more

The unit of magnetic flux is the Weber (Wb).

• The unit of magnetic flux is named after the German physicist Wilhelm Eduard Weber.

• One Weber is equal to one Tesla multiplied by one square meter.

• The Weber is a derived unit in the International System of Units (SI).

The electrodes used in arc heating are typically made of tungsten or carbon.

• Tungsten and carbon are commonly used materials for arc heating electrodes.

• Tungsten electrodes are preferred for high-temperature applications.

• Carbon electrodes are suitable for lower temperature operations.

• Other materials like graphite or metal alloys may also be used depending on the specific requirements.

The unit of resistance is ohm (Ω).

• Resistance is the measure of opposition to the flow of electric current.

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

• Resistance is denoted by the symbol 'R' and is measured using an ohmmeter.

• Common examples of resistance include resistors in electronic circuits and electrical wires.

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistanc...read more
