According to the Union University Department of Physics, when an electric current passes through a solid copper wire, the electrons move forward, but the protons within the positive atoms of copper do not. Electricity travelling through a wire moves at an extremely fast speed and is capable of powering anything from a light bulb to a laptop.Know More
Electrical energy is created by the movement of atoms containing positive, negative and neutral charges. Charge particles also come in the form of muons, positrons and antiprotons; however, the electricity contained in most electrical devices is limited to positive protons and negative electrons. Both electrons and protons carry electric charges of equal strength that can flow through solid metals. When the switch is turned on, electrons have to work their way through the billions of atoms in the wire in order to provide power to the connected appliance or electronic device.
According to SeaPerch, copper is a commonly used as a conductor in wires because it is more efficient and conductive than any other metal. Copper wires are also stronger compared to conductors, such as aluminum, which makes them more resistant to stretching, neck-down, creep, nicks and breaks. They are also an economical choice for electric companies since they do not require extra maintenance or complicated installation procedures.Learn More
The electric field strength of a uniform electric field is constant throughout the field. A perfectly uniform electric field has no variations in the entire field and is unattainable in the real world. However, two parallel plates can generate a field that resembles a perfectly uniform field with slight variations near the edge of the plates.Full Answer >
As a young boy, James Prescott Joule and his brother conducted electrical experiments by giving each other shocks. The boys also intentionally shocked the family's servants.Full Answer >
Standard electrode potential is the measure of the electrical potential of an electrochemical cell at its standard state. Standard electrode potential is calculated by measuring the energy per unit charge of the oxidation and reduction reactions that drive the electrochemical cell reaction.Full Answer >
The electromagnetic theory is a united theory of electromagnetism established by James Clerk Maxwell. This theory primarily discusses the relationships between electric field and magnetic field based from previous observations and experiments related to electricity, magnetism and optics combined.Full Answer >
