Q1: Thermal equivalent of electrical power in practical calculation is __________ kcal/kWh.

ANS:B - 3000

The value of 3000 kcal/kWh is not a standard conversion factor for the thermal equivalent of electrical power. It appears to be an incorrect or inaccurate value provided in error. In practical calculations, the commonly accepted value for the thermal equivalent of electrical power is approximately 860 kcal/kWh. This conversion factor is widely used to relate the energy content of electricity (measured in kilowatt-hours, kWh) to its equivalent energy in thermal units (kilocalories, kcal). The value of 3000 kcal/kWh does not accurately represent the thermal equivalent of electrical power and should not be used in calculations or conversions related to energy. It seems to be a mistaken inclusion or misunderstanding.
