A family uses 250 units of electrical energy during a mont. Calculate this electrical energy in joules. |
|
Answer» 250 units of electrical energy means 250 kWh of electrical energy. Now, we know that : 1 kWh of energy ` = 3.6 xx 10^(6) J` So, 250 kWh of energy `= 3.6 xx 10^(6) xx 250 J` `= 9 xx 10^(8)J` Thus, 250 units of electrical energy is equal to `9 xx 10^(8)` joules. |
