Jan 6, 2019 · Define unit vector and give its physical significance. A vector with magnitude unity but having specific direction is called unit vector. It's calculated by dividing given vector by its magnitude. It represents spatial direction of the particular quantity. Any vector quantity can be represented by product of its magnitude with unit vector.
Feb 2, 2020 · report flag outlined. Since, 1 Unit Electricity is the amount of electrical energy consumed by a load of 1 kW power rating in 1 hour. It is basically measurement unit of electrical energy consumption in Joule. 1 kWh (kilo watt hour) and 1 Unit are same. 1 kWh is the amount of energy consumption by 1 kW load in one hour. Therefore, 1 Unit = 1 kWh.
