1.) How gating of a thyristor works? A thyristor is a 4 layer 3 terminal device with 3 junctions. When the anode terminal has positive voltage and no gate voltage is applied‚ the first and the third junction are forward biased and the second junction is turned reverse biased allowing no current flow through the thyristor. A thyristor starts to conduct when the voltage across the anode and cathode (VAK) is increased beyond the thyristors breakdown voltage (VBO). This is

If the electrolyte solution is highly concentrated‚ then the amperage productions will also increase and vice versa. In a galvanic cell‚ the amperage is generated from flows of electrons between the two metals in the metal sulfate solution of the electrolyte. In order for a chemical reaction to take place‚ the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing

of humans. INVENTION OF BATTERIES: One of the most important inventions was that of portable electricity. Yes‚ batteries. The same thing that we put into our CD player‚ in our remote control‚ in our wireless mouse‚ in our car and the list goes on. Batteries are one of the most widely used forms of electrical energy‚ and it ’s hard to believe that the first battery ever created was way back in 1800. Alessandro Volta was the inventor of the first ever battery‚ which consisted of layers of

bill was getting too high‚ so I tried to think of a solution. Then I read an article about how a Prius battery could power a house‚ and then I thought about how I could power a house using a rechargeable battery like is found in the Prius. Then I came across the Bedini Wheel‚ an energy producing machine that runs on magnets. I could combine the Bedini Wheel energy to charge a Prius rechargeable battery to power a house’s electrical needs and all the appliances throughout the house. That would take care
