Question

An electric motor has a power rating 1.5 KW . How much work is done by the motor in 20s​

Answer 1

Given :-

• power, p = 1.5 KW = 1500W
• time, t = 20 sec

To Find :-

• Work done by the motor ?

Solution :-

we know that,

$\boxed{ \bold{power \: = \frac{work \: done}{time} }}$

$\bold{: \implies 1500 = \frac{w}{20} } \: \: \: \: \: \: \: \: \\ \\ \bold{: \implies w = 1500 \times 20 } \\ \\ \bold{: \implies w = 30000 \: j} \: \: \: \: \:$

hence, work done by motor is 30000 Joules or 30 Kilojoules
