What is the difference between electrical and electromagnetic energy?
Electric current is the movement of electric charge through a conductor. For example, an electric charge carried by electrons through a wire. An electromagnetic wave does not require a conductor. Electromagnetic waves are created by moving electric charges, but once created, they can propagate through a vacuum.
What can electromagnetic energy be converted into?
Electromagnetic Energy Transformations
Electromagnetic energy can be transformed to other forms of energy. For example, a solar panel converts light energy to electrical energy.
What are 3 examples of electromagnetic energy?
Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices.
What is an example of electrical energy in your home?
A lamp is plugged into a wall outlet. The electric current moves from the wall outlet into the light bulb in the lamp supplying electrical energy. When the electric charges slow down in the filament to light the light bulb, light energy is created.
What are the two types of electrical energy?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction.
