Another thing I like to point out is why we use AC for homes instead of DC. When we were building electrical grids, it was much simpler and easier to manipulate the voltage of AC than DC. A basic transformer is just two Coils of wire with different numbers of wrapping to change voltage up or down, so can run the main lines at thousands of volts up until you’re at the home where it steps down to 240v. The reason we need to do that is because higher voltages can carry power more efficiently. So generators can be further from homes.
Great teacher. The first person to explain this to me where it actually clicked and I immediately understood. The way it had been described to me in the past made me have a totally different idea of how an alternating current actually functions. This is much more natural and now everything makes sense! Thank you!!
Can you please answer these 3 questions (thanks in advance): - What were and are the ramifications of Lorentz's symmetrization of the Heaviside equations in 1892, and the continuing symmetrization of these equations today as the "electrical engineering model"? - What powers an electrical circuit, or what actually powers the electrical power grid? - There is the "source charge problem" or "the problem of the association of the fields and potentials and their energy, with their source charges". The charge sits there and pours out observable EM energy in 3-space in all directions, with absolutely no observable EM energy input. Piece of cake to prove that experimentally, anytime, anywhere so it's well-known. Either this "most difficult problem in classical and quantum electrodynamics" must be solved, or else one has totally destroyed the conservation of energy law itself. This is a recognized formidable problem, but very much "swept under the rug" and never discussed in "polite circles". So the question is: how does the energy gets input to a source charge or a source dipole in the first place?
the usefulness of AC current was, it was able to Step Up or Step down Voltages using transformers and transmitted from Generating stations to various parts of city and then Step down and supplied to a house or a locality.
To be noted: the big or tall towers you see in our elevtric grid is DC, and the smaller wooden poles in our streets and backyards are AC. The reason being DC can carry high voltage more efficiently in long distances. It can carry big blocks of energy without power loss.
Jason excellent video it gave a visual, it hard to leave suggestions as you see a large audience next video build something from your blue bin start with good old Guss and make a small flash light something people can walk around proud and they will say see what I made. You you see the vision. As for me I a little messed up hard to explain but my goals is to build a university like yours different approach but same tactics. You are amazing I don't even know how many people you helped. Thanks
Bro .so basically the. Eletron flow fromm neutral to phase and at somepoint mit flows from phase to neutral. How it can achieve eltrons flow from phase neutral since neutral has alot of eletrons
@@noobaccount7580even though it's a loop, we don't see the other things happening. Energy cannot always be contained, it always wants to travel somewhere else. Have you ever been charging your phone and the adapter heats up? That's because energy is being lost as heat, which is what happens to batteries. Also, the chemical reaction used inside batteries to create electricity can't be "turned off", so that's why batteries lose charge even when they're not being used.
@@jaydottt_transitfanner yeah, i just want to tell this guy that to create current flows it needs energy (you must have the magnet moving to create current). That's why you have electricity bills. I'm currently studying EE by the way.
AC is more suitable for long-distance power transmission. It can easily be transformed into higher or lower voltages using transformers, which reduces energy loss in transmission lines. DC, on the other hand, isn't as easy to transform, so it's not as efficient for long distance power distribution.
We generate ac purposefully because its much easier to transmit over long distances with much less loss, or voltage drop, than dc. If we used dc here to power homes, we would neeg generators every 5 miles.
Great question, the reason why we dont just use DC is because DC is hard on telephone cables, and can cause them to overheat and burn easily, therefore, DC is inefficient as far as traveling to our houses goes. AC is much easier on power lines, and therefore can travel much easier to our houses and appliances. DC is still used today for most curcuits, as it doesn’t need to travel through telephone cables when powering a circuit, as the AC going into your house is transformed into DC to power your breadboard circuit.
I am sorry but your explanation is not the best. Consider a magnet with a north and south pole. Then imagine the magnet rotating around the center of the poles. Next visualize the poles passing close to a copper wire. As each magnetic field passes the wire, pressure to move electrons first moves in one direction and then the opposite in the wire. Graphed over time it is shown as a sine curve: therefore AC.
AC current works with transformers as the alternating magnetic field produced by flowing charges (changing current) can induce a current in other wires (Faraday’s law). Because the equation for power loss in transmission lines is P=(I^2)R, and R is constant, we use transformers to reduce the amount of current in the wires by increasing the voltage between the points (P=VI). In short, we use AC in houses and transmission lines as it’s compatible with transformers (which aid in the reduction of power loss through heat in wires)
