Capitulo 24 The two plates of a capacitor hold +2800uC of charge‚ respectively‚ when the potential difference is 930V. What is the capacitance? [pic] How much charge flows from a 12.0-V battery when it is connected to a 12.6 u-F capacitor? [pic] An electric field of 4.80x10^5 V/m is desired between two parallel plates‚ each of area 21.0 cm2 and separated by 0.250cm of air. What charge must be on each plate? [pic] How strong is the electric field between two parallel plates of a 0.80-uF air-gap

Kelvin dropper Theory A normal uncharged piece of matter has equal numbers of positive and negative electric charges in each part of it‚ located close together‚ so no part of it has a net electric charge. The positive charges are the atoms’ nuclei which are bound into the structure of matter and are not free to move. The negative charges are the atoms’ electrons. In electrically conductive objects such as metals‚ some of the electrons are able to move freely about in the object. When a charged

Atoms Atom is the fundamental building block of all stuff‚ or what scientists like to call "matter". An individual atom is very small. In fact‚ the smallest type of atom‚ hydrogen‚ has a diameter of 10-8 cm. Every single object is composed of atoms. Our body is made up of many‚ many individual atoms. There are also many different types of atom. These different types are called elements. Examples of some elements are hydrogen‚ oxygen‚ and helium. Under normal conditions many atoms can stick together

the velocity of the conductor. The negative charges tend to move in one direction‚ and the positive charges in the opposite direction. This induced electric field‚ or motional emf‚ provides the basis for converting mechanical energy into electricalenergy. In conventional steam power plants‚ the heat released by the fuel is converted into rotational mechanical energy by means of a thermo cycle and the mechanical energy is then used to drive the electric generator. Thus two stages of energy conversion
