Our Electricity unit starts out learning about charges, attraction and repulsion. We deal with coulomb's law for forces, then move on to electric fields, both from single points and uniform distributions of charge. Our next step is to discuss electric potential as seen in these various fields. This is what is known as Voltage. Voltage is one of the most misunderstood pieces in electricity.
After studying voltage, equipotentials, and fields in the general sense, we move into circuits.
Electric circuits involve a voltage source, a conductor to carry the current, and various circuit elements. The most basic of which is the resistor. A light bulb is a common resistive element in a circuit. We also study capacitors and other basic circuit elements.
