Electrons are unique from the other particles in multiple ways. They exist outside of the nucleus, are significantly smaller in mass and exhibit both wave-like and particle-like characteristics. An electron is also anelementary particle, which means that it is not made up of smaller components....
Electron volt is defined as the energy acquired by an electron when it is accelerated through a potential difference of 1 volt. The value of electron volt (eV) is given as, 1 eV = (1.602 × 10-19 coulomb) × (1 volt) 1 eV = 1.602 × 10-19 joule ...
Electric fields provide us with the pushing force we need to induce current flow. An electric field in a circuit is like an electron pump: a large source of negative charges that can propel electrons, which will flow through the circuit towards the positive lump of charges. Electric Potential...
What is the difference between electric current and electron flow? Why are they in different directions? There is still a lot of confusion on this issue. It comes from when Benjamin Franklin first discovered electricity he thought it was positive charges that was moving along the wire. So the...
In 2014, physicists thought they'd detected a 3.5 kiloelectron volt signal (keV) coming from deep within the Milky Way. This signal was believed to be consistent with what would arise from decaying sterile neutrino dark matter. In 2020, equipped with new data from the XMM-Newton space X-...
What is the kinetic energy of an electron with a velocity of 3551 m/s ? (Answer in units of J) A 1.5-V alkaline D battery can provide about 42,100 J of electric energy. If a current of 1.50 A flows through the two D batteries while they're in th...
The maximum loss of energy occurs when there is a head-on collision, and the photon is scattered back in the direction from where it arrived. Answer and Explanation: Compton scattering of a photon from an electron re...
The electron carries a charge. But there are other particles that carry charge in a circuit too. For exampleelectron holesthat move from plus to minus. And they can both exist in the same circuit. Electrons are the most common particle that flow in an electric circuit. So shouldn’t we ...
They work in the same way, producing electricity from electron exchanges, but have different strengths and weaknesses. The soil-based earth battery can produce up to 5 volts per single battery, which is more than enough to power a small electronic device with an LCD screen such as a calcul...
What would happen if you use a 12-volt battery and a 12-volt light bulb to get 100 watts of power? I = 100 W/12 V = 8.33 amps So, this latter system produces the same power, but with half the current. There is an advantage that comes from using less current to make the same ...
