Power of a lamp = 100W
a) When time taken is 1 second,
Power = Energy consumed/ Time taken
Energy consumed = 100 x 1 = 100 J
b) When time taken is 1 minute = 60 seconds,
Power = Energy consumed/ Time taken
Energy consumed = 100 x 60 = 6000 J = 6 kJ
a) When time taken is 1 second,
Power = Energy consumed/ Time taken
Energy consumed = 100 x 1 = 100 J
b) When time taken is 1 minute = 60 seconds,
Power = Energy consumed/ Time taken
Energy consumed = 100 x 60 = 6000 J = 6 kJ

Answer:6
Explanation:FIRST WE CONVERT WALT TO KILOWALT
THEREFORE , POWER OF LAMP=100WALT=0.1 KILOWALT
THEN WE CONVERT 1 MINUTE = SO,1MIN=60 SECS
FORMULA = P×t
60×0.1=6
