    V=W/Q is often remembered wrongly. In questions where you have to check the resistance from the graph see what is plotted along the x and y axis. Reason why alloys are used to make elements of electric irons and heaters is not because they are insulators. 2. Units 3. 4. Formula Graphs 5. Resistivity 6. Change in resistance If a wire is folded(doubled on it) and made half its length‚ then the resistance does not become half. 7. Resistors in series Is the current

    The main fact people need to know in order to understand “What is the Fastest Way to Cool a Soda?” is that placing objects in ice-as well as freezers and refrigerators-makes them colder. How does the object become cooler by being placed in ice? When you add ice to a warm drink‚ some of the drinks’ thermal energy is transferred to the ice (that is why the ice will melt in the drink) which makes the drink cooler. To thoroughly comprehend the project‚ more research and knowledge is required. There

    What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

    non-zero‚ unlike an insulator‚ yet still several magnitudes smaller than that of a conductor. There exists a significant energy gap between the filled valence – highest range of electron energies normally present at absolute zero – and empty conduction bands – range of energies which are enough to unbind the electron from the atom and allow it to move freely within the atomic lattice – in a semiconductor‚ unlike a conductor which has very small or no band gaps and/or an insulator which has very large
