Question

electric appliance of power 2 kilowatt is used for 30 minutes to press clothes calculate the energy consumed in joules​

Answer 1

$\huge{\underline{\mathfrak{\green{Answer}}}}$

$\large{\star{\gray{\sf{Given}}}}$

• Power (p) = 2 kwh
• Time taken (t) = 30 mins = 1/2 hours

$\rule{200}{2}$

$\large{\star{\gray{\sf{To \: Find}}}}$

We have to find Work done in joules.

$\rule{200}{2}$

$\large{\star{\gray{\sf{Solution}}}}$

We know that

$\Large{\star{\boxed{\boxed{\purple{\sf{Work = Power \times Time}}}}}}$

______________[Put Values]

$\sf{→Work = 2 \times \frac{1}{2}} \\ \\ \sf{→ Work = 1 \: kwh}$

As, we have to find value in joules. So, we will multiple it by $\sf{3.6 \times 10^6}$

$\sf{→ Work = 1 \times 3.6 \times 10^6} \\ \\ \sf{→ Work = 3.6 \times 10^{6} \: joules}$

$\large{\star{\boxed{\boxed{\orange{\sf{Work = 3.6 \times 10^6}}}}}}$
