Dielectrics: A parallel-plate capacitor with plate separation of 1.0 cm has square plates, each with an area of 6.0 × 10-2 m2. What is the capacitance of this capacitor if a dielectric material with a dielectric constant of 2.4 is placed between the plates, completely filling them? (

Ohm’s law: When a voltage difference is applied to a piece of metal wire, a 5.0 mA current flows through it. If this metal wire is now replaced with a silver wire having twice the diameter of the original wire, how much current will flow through the silver wire? The lengths of both wires are the same, and the voltage difference remains unchanged. (The resistivity of the original metal is 1.68 × 10-8
