Solution

The energy transferred by an appliance is given by the formula:

Energy (E) = Power (P) x Time (T)

where:

  • Power (P) is given as 100 W (Watts)
  • Time (T) is given as 15 s (seconds)

Substituting the given values into the formula, we get:

E = 100 W x 15 s = 1500 J (Joules)

So, the energy transferred by a 100 W appliance in 15 s is 1500 Joules.
