A lamp consumes 1000 J of electrical energy in 10 s. What is its power ?

Consumption of electrical energy by the lamp $w=1000\ J$

Time taken to consume the electrical energy by the lamp $t=10\ s$

Power of the lamp $P=\frac{w}{t}$

$=\frac{1000\ J}{5\ s}$

$=100\ Watt$
 

Thus, the power of the lamp is $100\ watt$.
