Electrical Circuit

We have seen that when we consider two vessels that have an unequal level of water in them, that is, vessel A and vessel B have differing amounts of water. So under such a circumstance, when these vessels will be connected with the pipe, water will flow and we saw that in our previous lecture.…

Electricity and Electric Circuits

Hi. It’s Mr. Andersen and today I’m going to be talking about electricity and electric circuits. Scientists have known about electricity for a long time. In fact the word actually comes from the word amber. Because they realized that you could rub amber, which is essentially dried out sap with fur and you could generate…

Series and Parallel Circuits

Hi. It’s Mr. Andersen and today I’m going to be talking about series and parallel circuits. These are a couple of different circuit diagrams. Remember this stands for a battery and each of those stand for a resistor. And so this would be a series circuit. Remember it’s a closed circuit, so there’s a loop…

Circuit Breaker Testing

Circuit breakers allow the flow of energy to be controlled by safely switching currents on and off at all voltage levels of the energy grid. In the open position, they have to ensure isolation across the switching distance, between phases, and to ground. In the closed position they have to allow the energy to flow…
