2. An electric circuit is a closed path in whichcurrent flows. In general ,a circuit has the followingcomponents:-(1.)A source of electric current such as a batteryof one or more cells.(2.)Connecting wires which are normallyinsulated copper wires.(3.)An appliance which is using the current ,fore.g. a bulb or an electric iron.(4.)A key which is a switch. 3. When you switch on an electrictorch the bulb glows and gives offlight. The bulb glows because, whenyou press the torch. The switch,electric current flows from thebattery in the torch to the bulbthrough conducting metal strips inthe conducting strips provide aclosed path for the current to flow. 4.
