What Are The Kinds Of Circuits?
Two kinds of electrical circuits are frequently used, the series circuit and the parallel circuit. In series circuit, the same current passes through all the resistances. For example, three bulbs are placed in series. If any one of them fails to allow current to flow through it, all three bulbs will stop working. In a parallel circuit, each resistance is connecting separately. Thus, if any of the three bulbs in parallel fails to allow current to pass through it, the other two will still continuously work. A current flows around a circuit because the cell, which is the source of the current, forces it to do so. The terminal of the cell can be considered to be at different ‘electrical pressures’, more correctly termed ‘electrical potential’. As in water, where the difference is pressure causes water to flow from a high pressure area to a low pressure area.An electric current can continually flow along a wire only if the wire forms a complete path or circuit. As the current travels along
