Refex Energy Interview Questions and Answers

Voltage is the potential difference between two points in a circuit, while current is the flow of electric charge through a conductor.

• Voltage is measured in volts (V) and represents the potential energy difference between two points in a circuit.

• Current is measured in amperes (A) and represents the flow of electric charge through a conductor.

• Voltage is analogous to the pressure in a water pipe, while current is analogo...read more

Modulation is the process of varying a carrier signal to transmit information. Types include amplitude modulation, frequency modulation, and phase modulation.

• Modulation is the process of varying a carrier signal to transmit information

• Types of modulation include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM)

• AM varies the amplitude of the carrier signal based on the input signal

• FM varies...read more

To convert kW to MW, divide the power in kW by 1000.

• To convert kW to MW, divide the power in kW by 1000.

• For example, 500 kW is equal to 0.5 MW (500 kW / 1000 = 0.5 MW).

Unit of power is the rate at which work is done or energy is transferred.

• Unit of power is measured in watts (W)

• 1 watt is equal to 1 joule per second

• Power can also be measured in horsepower (hp) in some contexts
