Explain how voltage current and resistance could interact to give a person a severe electrical shock if he or she touched an electrical wire in the wrong way. Do superconductors have electric power? Explain. What causes electric shock - current or voltage?
If voltage stays the same, but resistance goes up, what happens to amperage? Calculate the current in a 195V circuit if the resistance is 13M Ohms. Find the current I_1, I_2, I_3 flowing through resistors and their po...
In addition, analytical recombination resistance is composed by the alternating current(AC) recombination resistance(Rrac) and the direct current(DC) recombination resistance(Rrdc), which are caused by small-signal perturbation and the DC bias voltage, respectively. Both of two parts will decrease ...

Superconductivity, in which electric current flows without resistance, promises significant energy savings, but for everyday applications such as low-voltage electric grids with no transmission losses or superefficienct motors and generators, conventional superconductivity can’t do the job. Superconductors ...
Working : During the first half cycle of input signal, S being at positive potential, D1 is forward biased and D2 is reverse biased. D1 offers low resistance to the charge carriers whereas D2 offers very high resistance to charge carriers. Therefore forward current flows in D1 due to ...
To conclude, both the IV characteristics of forward bias and reverse bias are different. In forward bias, there is an easy path for the flow of current, while in reverse bias, forward current is small. As the depletion layer is thick, there is higher resistance to the flow o...
a feather will hit the ground more slowly than a stone because air resistance slows the feather down as it falls. Interestingly, when scientists from the Apollo 15 mission went to the moon (where there is no air resistance to slow feathers down), they carried out the feather and stone expe...
(current). So, in a system where there is no current (creating a divide by zero error), and there is no voltage (no change in electron work capacity, because we don't have a way to excite the electrons, because there is no power) Resistance is incalculable.lcarsos(talk) 22:22, 20...
