<span style="font-size: large;">A Capacitor is a component used to store electric charge. Basically an electric field is formed and charge is stored electrostatically. There are different types of capacitors but basic principal is always same that is two conductors separated by an insulator. Capacitance of a capacitor is measured in farads(usually <span style="background-color: white; color: #333333; font-family: arial, verdana, sans-serif; line-height: 20px;">μF, </span><span style="background-color: white; color: #333333; font-family: arial, verdana, sans-serif; line-height: 20px;">nF,</span><span style="background-color: white; color: #333333; font-family: arial, verdana, sans-serif; line-height: 20px;"> pF </span>).</span></div>
<div>
<span style="font-size: large;"><br /></span></div>
<div>
<span style="font-size: large;">Capacitance C = Q(charge) / V(voltage)</span></div>
<div>
<span style="font-size: large;"><br /></span></div>
<div>
<span style="font-size: large;">Most commonly used Types of capacitors are<i> Electrolytic</i> and <i>Ceramic disk.</i></span></div>

Transistor is a revolutionary component the field of electronics it decreased the size as well as price of devices such as computers .These are the building blocks of electronic devices. Transistors come as individual packages as well as found embedded in Integrated Circuits(ICs).</span></div>

<span style="font-size: large;"><b>Inductor </b></span><br />
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<span style="font-size: large;">Inductor is a two terminal electrical component that resist changes in electric current flowing through it. It is basically a conductor e.g wire wound into a shape of a coil. When current is passed through an inductor a magnetic field is created temporarily storing energy when flowing current changes, a voltage is induced in the inductor by magnetic field, opposing the change in current that created it.</span><br />
