volt = electronvolt / elementary chargeorV = eV / e ExampleWhat is the voltage supply in volts of an electrical circuit with energy consumption of 800 electron-volts and charge flow of 40 electron charges?V = 800eV / 40e = 20V
While there are many different types of batteries, the basic concept by which they function remains the same. When a device is connected to a battery, a reaction occurs that produces electrical energy. This is known as an electrochemical reaction. Italian physicist Count Alessandro Volta first dis...

Current is the measure of how many electrons are flowing through a conductor--the more electrons flowing, the higher the current. Keep this in mind when thinking about amp circuits, high voltage is an extreme scarcity of electrons and ground represents an unlimited supply of electrons.As...
Radiation can have different energy levels, energies which are measured in electron-volts (eV). One electron-volt is defined as the amount of energy gained by one electron as it moves through an electric field of one volt. For example, green light photons usually have an energy of about 2.3...
Calculate the energy of a photon, in kiloelectron volts (KeV), which has a wavelength of 0.234A. How do you convert electricity units to kWh? How is energy from the Sun distributed around Earth? What is the frequency of light in which each quantum pack has 8 x 10^-19 power joule of...
How many amperes flow through a 60-watt bulb when 120 volts are impressed across it? Power: The total power generated in a complete circuit is equal to the product of voltage and the amount of current flowing in the circuit. Based on Ohm's law, the voltage of a...
Resistance is one of the most basic concepts that physics students learn about electricity. If you picture electricity as a group of electrons flowing through a wire to create current, then resistance is a measure of a material's inherent barriers to ele
electrical pulses that have very high electrical power, meaning both high voltage – up to a few megavolts – and large electrical currents – tens of kiloamps. That’s more voltage than the highest-voltage long-distance power transmission lines, and about the amount of current i...
when the engine begins generating electrical energy through a device called an alternator. As for disadvantages, lead-acid batteries are relatively big, surprisingly heavy (try lifting one!), expensive, and can't be fully charged and discharged too many times. Another problem is their use of tox...
