For the three-way bulb (50 W, 100 W, 150 W) find the resistance of: a. the 100-W filament
b. the 50-W filament.

Assume that the wattage ratings are not limited by significant figures and ignore any heating effects on the resistances

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
