Electric circuit example sentences

Figureure 1 1 shows the schematic diagram of a typical electric circuit comprising a cell, an electric bulb, an ammeter and a plug key.In electric circuits, the unavoidable heating can increase the temperature of the components and alter their properties.You will observe that the value of the current in the ammeter is the same, independent of its position in the electric circuit.In an electric circuit, a device called rheostat is often used to change the resistance in the circuit.On the other hand, if the electric circuit is purely resistive, that is, a configureuration of resistors only connected to a battery; the source energy continually gets dissipated entirely in the form of heat.We know that motion of electrons in an electric circuit constitutes an electric current.A continuous and closed path of an electric current is called an electric circuit.Conventionally, in an electric circuit the direction of electric current is taken as opposite to the direction of the flow of electrons, which are negative charges.What constitutes electricity? How does it flow in an electric circuit? What are the factors that control or regulate the current through an electric circuit? In this Chapter, we shall attempt to answer such questions.Figureure 1 6 shows an electric circuit in which three resistors having resistances R1, R2 and R3, respectively, are joined end to end.Another common application of Joule's heating is the fuse used in electric circuits.In many practical cases it is necessary to increase or decrease the current in an electric circuit.In order to maintain the current in a given electric circuit, the cell has to expend its chemical energy stored in it.We know that an electric circuit, as shown in Figureure 1 1, comprises a cell (or a battery), a plug key, electrical component(s), and connecting wires.Many people think that electrons are consumed in an electric circuit.
