Every short circuit is always a closed circuit while every closed circuit is not a short circuit?
Long winded but true.
Nothing about a series circuit is necessarily constant. You may be thinking of the current, which is the same number at any point in a series circuit. That doesn't mean that it can't change. But if it does change, it'll change at every point, and still be the same number everywhere in the series circuit.
Which word or words are unnecessary in the following sentence your father always puts the coffee on to brew every day?
Every outlet in a home is in parallel with every other outlet in the home. In fact, they're also all in parallel with every outlet in the home of every neighbor served by the same pole transformer. We all know that industries, and especially public utilities, always do everything in the most efficient, most beneficial, and all-around best way for everybody. So since parallel is how they always do it, we can be sure that…
How does the direction of an electrical circuit move on a battery device differ from the direction of an ac current?
In a DC circuit (battery), the lower potential is always on one 'end' of the circuit so the current always flows in the same direction. In a AC circuit, a wave is generated so each end cycles between high and low potential. Current always flows towards lower potential and changes direction every time the higher/ lower potential changes
electricity take every possible path which follow closed path across its source. Answer In a series circuit, there is only one path for current to flow; the same current passes through each component. In a parallel circuit, there are multiple paths called 'branches', and the sum of the individual branch currents is equal to the current drawn from the supply.
Its not mandatory in every case, this is recommanded to utilise the electrisity used for energising the transformer. Closed means putting some load.But if we talk about Current Transformer(CT) then yes CT's senondry must be close every time otherwise there will be a high emf in secondary of CT and can damage the instrument as well as operator because its a step up transformer.
