Electricity is an important chapter in the class 10 CBSE science syllabus. The concept of electricity provides the base to study electricity and magnetism when you go for higher studies.

In this chapter, students will come across questions such as what is electricity? What constitutes electricity? What flows in an electric current? How can you control electric circuits?

All of us hear the word electricity every day. But, do you know what constitutes electricity? Do you know how electric current is generated? If you have wondered and thought about all these questions, this chapter will help you understand the fundamentals.

Electricity, in simple words, can be described as a form of energy that exists due to the existence of charged particles. The easiest way to describe electric current is the amount of charge flowing through a particular area per unit of time.

&=\sqrt{s(s-a)(s-b)(s-c)} \\

&=\sqrt{\frac{3 a}{2}\left(\frac{3 a}{2}-a\right)\left(\frac{3 a}{2}-a\right)\left(\frac{3 a}{2}-a\right)} \\

&=\sqrt{\frac{3 a}{2} \times \frac{a}{2} \times \frac{a}{2} \times \frac{a}{2}} \\

&=\sqrt{\frac{3 a^{4}}{16}} \\

&=\sqrt{3} \frac{a^{2}}{16} \\

&=\sqrt{3} \frac{a^{2}}{4} \\

&=\frac{\sqrt{3}}{4} \times 60 \times 60 \\

&=901 \sqrt{3} \mathrm{~cm}^{2}

$=\sqrt{s(s-a)(s-b)(s-c)}$

$=\sqrt{\frac{3 a}{2}\left(\frac{3 a}{2}-a\right)\left(\frac{3 a}{2}-a\right)\left(\frac{3 a}{2}-a\right)}$

$=\sqrt{\frac{3 a}{2} \times \frac{a}{2} \times \frac{a}{2} \times \frac{a}{2}}$

$=\sqrt{\frac{3 a^{4}}{16}}$

$=\sqrt{3} \frac{a^{2}}{16}$

$=\sqrt{3} \frac{a^{2}}{4}$

$=\frac{\sqrt{3}}{4} \times 60 \times 60$

$=900 \sqrt{3} \mathrm{~cm}^{2}$
