Lightning What causes sparks b/w clothing when taking them out of the dryer? Static discharge What length of time does a static discharge last? Fraction of a second What causes a shock on a dry summer day when touching a doorknob? Extra electrons from carpet to shoes through your body b/c skin is a conductor to the doorknob which is also a conductor What type of circuit is this? series What type of circuit is this? Parallel A circuit that allows only one route for an electric current to follow series A circuit that has two or more branches for electrons to follow parallel What type of circuits do homes use for their wiring? parallel A device that increases or decreases voltage ina power line transformer free free what is an example of when a generator is used? Power lines cars What are these type of transformers? Step up Step down Generators change one form of energy to another, what does it change? Mechanical to electrical What determines the strength of an electromagnet? List two Current going to it Number of coils What are two types of metals that can become electromagnets? Cobalt Nickel iron Atoms in a magnet are: a. Arranged randomly a. Negatively charged b. Positively charged c. Aligned according to magnetic feilds Aligned according to magnetic fields If you have a copper wire, permanent magnet and an iron rod, what can you do to produce an electrical current? a. Place the wire near the north pole of the magnet b. Move the permanent magnet rapidly over the wire c. Touch the ends of the wire to the poles of the magnet b. Move the permanent magnet rapidly over the wire A credit card works by moving a magnetic strip past a wire coil, what type of energy is being created by the changing magnetic field? electrical Region around the magnet where the magnetic force acts Magnetic field What is resistance measured in? ohms Where is the magnetic force of a magnet the strongest? poles A temporary magnet made by placing an iron core inside a current-carrying wire electromagnet Process of producing an electric current by moving a lopp of wire around an iron core Electromagnetic induction Make your wager What is the flow of energy for the following? • Each use three types of energy a. Steam turning a paddle wheel to work an electromagnet to light a light bulb b. A battery giving current to an electromagnet to make a speaker work a.Mechanical – electrical – thermal b.
