ELECTROMAGNET COILS USE UP ENERGY TO MAKE MAGNETISM? (William J. Beaty)
Not right. Sustaining a magnetic field requires no energy. Coils only require energy to initially create a magnetic field. They […]

No. They only travel at 186,000 miles per second while in a perfect vacuum. Light waves travel a bit slower
Wrong. Electric power cannot be made to flow. Power is defined as “flow of energy.” Saying that power “flows” is
Wrong. “Static electricity” exists whenever there are unequal amounts of positive and negative charged particles present. It doesn’t matter whether
The conventional view is that static electricity is created through charge separation which means that there is always equal quantities
WRONG “Static” electricity appears whenever two dissimilar insulating materials are placed into intimate contact and then separated again. All that’s
No. The word “charge” has more than one meaning, and the meanings contradict each other. The “charge” in a battery
Wrong. Some books teach that, in a simple battery/bulb circuit, each electron carries energy to the bulb, is emptied of
Not quite. The actual path of electric current is THROUGH the battery. Some books imply (or even state outright) that,
Wrong. Electric current is a flowing motion of charged particles. The words “Electric Current” mean the same as “charge flow.”
Horribly misleading! Most textbooks discuss a substance/energy called “current”. They constantly talk about flows of current. However, here is a
Wrong. “Static” appears whenever the negative charges within matter are separated from the positive charges. “Current” appears whenever the negative
Nope. Static and Current are two ways in which electrical charges can behave. If we said that Electrical Science is
Wrong. When you connect a light bulb to a battery, energy moves from the battery to the bulb. This is
Wrong. In metals, electric current is a flow of electrons. Many books claim that these electrons flow at the speed
Wrong. When individual atoms of copper are brought together to form a bulk metal material, something unexpected happens. The outer
Wrong. Electric currents in copper wires are a flow of electrons, but these electrons are not supplied by batteries. They
Wrong. Actually, “Electricity” does not exist. The term “electricity” is a catch-all word with many meanings. Unfortunately these meanings are
