You use an electrical generator with a hand crank to power a small radio. While cranking, you note the voltage reading measured across a capacitor that is used to store all the energy you're cranking out using your muscles. After an hour, you see the voltage reading is 2.2V. The capacitor has a capacitance of 3.5 x10-6F. You averaged 3.4 rotations on the crank every second. How much energy did your muscles donate to the radio's capacitor? (Give your answer in x10-6J)
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
