Electrical Engineering Questions
• Do you know how to measure the earth resistance? Actually the Earth resistance is measured using “earth resistance meter”. You might have also heard that using megger, but megger is used only for high resistance measurement i.e., in Mega ohms but when considereing upon earth resistance it should not exceed 1ohm so earth resistance […]

Electric Power
Electric Power Electric power is generally defined that it is the product of current and voltage in an electric circuit. But it does not clear the concept. Although, Electric power is the rate at which electric energy is consumed in an electric circuit. It tell us how fast a electric circuit is consuming energy. Electric energy is usually converted […]
