Down: 1) One of the four fundamental forces. The force that acts between all charged particles, whether or not they're moving. 2) involves the contact of a charged object to a neutral object. In contrast to induction, where the charged object is brought near but never contacted to the object being charged, conducted charging involves making the physical connection of the charged object to the neutral object.4) is the flow of a positive charge from positive to negative and is the reverse of real electron flow.5) s an electrical quantity that measures how the device or material reduces the electric current flow through it. The resistance is measured in units of ohms7) is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.8) a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.9) was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis. Across: 3) was a Scottish scientist in the field of mathematical physics. His most notable achievement was to formulate the classical theory of electromagnetic radiation, bringing together for the first time electricity, magnetism, and light as different manifestations of the same phenomenon.6) an electrical circuit that is not complete 10) is a method used to charge an object without actually touching the object to any other charged object. An understanding of charging by induction requires an understanding of the nature of a conductor and an understanding of the polarization process.
