The unit of electrical energy is kWh. 1 kWh is the energy used in one hour at a rate of 1000J/s.
1 kWh = 3.6× 10^6
1 kWh = 1 unit
400 units/ 400 kWh= 400× 3.6×10^6 J
400 units= 144× 10^7.
Plz mark it as the brainlest.......

vanshika2002: sry I forgot to write J in the answer so the final ans. is 144×10^7 J

vanshika2002: plz mark it as the brainliest..
