a microwave oven has a power rating of 850 w. If the microwave oven is turned on for 6 minutes ,how much energy will it use?
state the units in your answer



Answer :

Power is given by;

[tex]P = \frac{E}{t} [/tex]

850    = [tex] \frac{E}{6 * 60} [/tex]
  
      E = 850 * 360
    
      E = 306000
   
      E = 306 kJ
