<p>In <a data-page="136" href="https://app.ulearngo.com/tutorials/electric-charge-and-electric-field/">Electric Charge and Electric Field</a>, we just scratched the surface (or at least rubbed it) of electrical phenomena. Two of the most familiar aspects of electricity are its energy and <em>voltage</em>. We know, for example, that great amounts of electrical energy can be stored in batteries, are transmitted cross-country through power lines, and may jump from clouds to explode the sap of trees. In a similar manner, at molecular levels, <em>ions</em> cross cell membranes and transfer information.</p>
<p>We also know about voltages associated with electricity. Batteries are typically a few volts, the outlets in your home produce 120 volts, and power lines can be as high as hundreds of thousands of volts. But energy and voltage are not the same thing. A motorcycle battery, for example, is small and would not be very successful in replacing the much larger car battery, yet each has the same voltage. In this tutorial, we shall examine the relationship between voltage and electrical energy and begin to explore some of the many applications of electricity.</p>

Introduction to Electric Potential and Electric Energy

Physics is a science discipline concerned with the nature and properties of matter and energy. Physics topics include mechanics, heat, light and radiation, sound, electricity, magnetism, the structure of atoms, and so on.

Physics

Discover how electric potential and electric field are related, explore the concepts of energy conservation, potential difference, capacitance, and equipotential lines, and learn how to calculate energy stored in capacitors.
