... cause the wire in this example to melt! (Recall from Equation 18-24 in Section 18-6 that the power into a resistor with resistance R that carries current i is P = i2R. The wire in this example has a small cross-sectional area, so its resistance R will be fairly large. The power delivered to the wire ...

... The rod carries a total positive charge +Q uniformly distributed over its length. A negative point charge -q is placed at the origin. What is the electric force on the point charge? Express your answer in unit vector notation. You could start with Coulomb’s Law, rewrite it to calculate the dF on q1= ...
