🚀Fun Fact: Did you know? When we talk about &quot;work&quot; in physics, we aren&#39;t referring to your chores or homework! Instead, it&rsquo;s about moving objects in the presence of forces.

<ul>
	<li>Definition: An equipotential surface is where every point on that surface has the same electric potential. Imagine a magical sphere around a charge where every point on that sphere feels the exact same force. Cool, right?</li>
	<li>Understanding Equipotential: Think of two astronauts, X and Y, floating towards a planet (the point charge) from far, far away (infinity). Even if they land in different spots, as long as they are the same distance from the planet, they&#39;ll feel the same gravity pull (or in our case, electric potential). Hence, they&#39;re on an equipotential surface!</li>
	<li>Always 90&deg;!
	<ul>
		<li>Equipotential surfaces and electric field lines always meet at 90&deg;.</li>
		<li>Just like the crisscross pattern of a basketball&#39;s lines! 🏀</li>
	</ul>
	</li>
</ul>

<ul>
	<li>Uniform Field Pattern: Picture two parallel plates, like two slices of bread. If they&#39;re charged, the field lines between them will be as evenly spaced as the jam on your PB&amp;J sandwich!</li>
	<li>Potential Difference: Imagine one plate is a +12V battery and the other is ground. A positive charge, like a ball, will roll down the hill (from +12V to 0V). A negative charge will need a push to go the same way since it&#39;s being repelled by the 0V plate.</li>
</ul>

Materials Needed

<ul>
	<li>&quot;Teledeltos&quot; paper (with graphite coating)</li>
	<li>6V power supply (AA batteries will do)</li>
	<li>Copper foil strips</li>
	<li>Bulldog clips, a voltmeter (or oscilloscope)</li>
	<li>Connecting leads</li>
</ul>

Steps

<ul>
	<li>Setup as in Figure 26 (not provided, but remember, proper connections are key!).</li>
	<li>Paint the connections using a conducting liquid (a mix of graphite &amp; water) for better results.</li>
	<li>Probe the paper with the voltmeter to find areas of the same voltage, and mark them.</li>
	<li>Explore different configurations. Want a challenge? Try simulating a point charge using a sewing needle!</li>
</ul>

Cool Fact: This setup helps visualize 2D equipotentials. Want 3D? Use the same setup with a tank of copper (ii) sulfate solution and two copper plates. It&#39;s like jumping from a game of chess to 3D chess!

<ul>
	<li>Equipotential Surfaces in 3D: Imagine sheets floating in space, always perpendicular to electric field lines.</li>
	<li>Equipotential Volumes: This is like a magic room where every single point in the room has the same potential. A solid conductor, for instance, is an equipotential volume.</li>
</ul>

<ul>
	<li>Equipotential surfaces link points of the same potential.</li>
	<li>Charges can dance 💃 on these surfaces without any work being done.</li>
	<li>Electric field lines always cut these surfaces at a right angle (90&deg;).</li>
	<li>Potential is scalar (has no direction, just magnitude).</li>
	<li>Equipotential lines with different values are like parallel universes &ndash; they never meet!</li>
</ul>
