Livguard Sales Interview Questions and Answers

An inverter is an electronic device that converts DC power to AC power.

• Inverters are commonly used in solar power systems to convert DC power from solar panels to AC power for use in homes and businesses.

• They are also used in cars to convert DC power from the battery to AC power for charging devices.

• Inverters come in various sizes and capacities, from small portable units to large industrial models.

• They can be pure sin...read more

The ampere is the SI unit of electric current, representing the flow of electric charge.

• The ampere is named after the French mathematician and physicist André-Marie Ampère.

• It is defined as one coulomb of charge passing through a conductor per second.

• The ampere is used to measure the intensity of electric current in a circuit.

• It is a fundamental unit in the International System of Units (SI).

A battery is a device that stores chemical energy and converts it into electrical energy.

• A battery consists of one or more electrochemical cells.

• It is commonly used to power electronic devices such as smartphones, laptops, and cars.

• Batteries can be rechargeable or non-rechargeable.

• They provide a portable and convenient source of power.

• Examples of batteries include alkaline batteries, lithium-ion batteries, and lead-aci

DC stands for Direct Current.

• DC is a type of electric current that flows in one direction.

• It is commonly used in batteries, electronic devices, and power transmission systems.

• Unlike AC (Alternating Current), DC does not change direction periodically.

• DC voltage can be either positive or negative depending on the direction of current flow.

• Examples of DC devices include smartphones, laptops, and electric vehicles.

AC stands for Alternating Current.

• AC is a type of electrical current that periodically reverses direction.

• It is commonly used in household appliances and electrical power transmission.

• AC voltage can be easily changed using transformers.

• AC is different from DC (Direct Current) which flows in only one direction.

• AC can be dangerous if not handled properly.

Current is the flow of electric charge through a conductor.

• Current is measured in amperes (A)

• It is caused by the movement of electrons

• Current can be either direct current (DC) or alternating current (AC)

• DC flows in one direction while AC alternates in direction

• Examples of current include the flow of electricity in a circuit or the flow of water in a river

S is a letter in the English alphabet.

• S is the 19th letter of the English alphabet.

• It is a consonant.

• It is often used as an abbreviation for words such as 'South' or 'Sunday'.
