Define the following: Flux density Coercive force Residual magnetism Saturation

It refers to the flow of electric charges during a short period of time when the electrons are in motion.  Select one: a. CONDUCTION b. MAGNETIC MOTION c. DOPPLER EFFECT d. BIASING ..... ....

If we stretch a copper rod, making it 0.1% longer, how much will its resistance change? What behavior do we assume for copper in deformation?

A copper conductor has a diameter of 0.6 in and it is 1200 ft long. Assume that it carries a total dc current of 50 A. Find the total resistance of the conductor and the current density. The resistivity of copper is 1.72 x 10-8 2-m.

Diagram of the problem, necessary formulas, clearance and numerical solution. A steady current of 0.5 A flows through a wire. How much charge passes through the wire in one minute?

Draw a simple circuit, label the parts and write brief explanations on how these parts work in a circuit/identify their functions. Include the electromotive force in the one of the explanations.

QUESTION 1 While it is common for electricity to be caused by the flow of electrons, we know that electric current can also flow whenever a. a constant magnetic field is present b. conductors are isolated. C. electrons, protons, or other charged particles move. d. dipoles are aligned.

How does Coulomb's law relate to the behavior of electric charges in materials such as conductors and insulators?
