A) 15 unit
B) 60 unit
C) 120 unit
D) 240 unit
Correct Answer: B
Solution :
Key Idea: The rate at which electrical energy \[\left( W \right)\] is dissipated into other from of energy is called electric power \[\left( P \right)\] Power=rate of electrical energy \[\Rightarrow \] \[P\frac{W}{t}\] \[\Rightarrow \] \[W=pt=2\,kW\times 1\,h=2\,kWh\] Also 1 kWh or 1 unit is the quantity of electric energy which is dissipated in 1 h in a circuit when the electric power in the circuit is 1 kWh. \[\therefore \]Energy consumed in 30 days \[=2\times 30=60\,kWh=60\,units\].You need to login to perform this action.
