Bulb glows only in open circuit
WebAnswer: (a) Closed Circuit. The bulb lights in a complete circuit because current is flowing. To glow, a bulb requires adequate current flow. When the current passes through the bulb, the filament heats up and glows, emitting heat and light. If the loop is open, however, the electricity cannot flow through it, and the lightbulb will stop burning. WebStatement-1: There is very less current flows when an electric circuit is open. Statement-2: When the switch of an electric circuit is in off mode, the circuit is said to be open. Statement-3: One can get a shock in open …

WebIn a complete circuit, the light bulb glows because the current is flowing. A light bulb requires a sufficient current flow to light up. As the current moves, the lightbulb's filament begins to heat up and glow, giving off heat and light. Hence, the bulb glows in a closed … WebOpen in App. Solution. The bulb glows only if the circuit is closed and electric current is passed through it. So inorder to make the bulb glow, the components have to be connected in a way that the circuit is closed and provides a path for current to flow. The complete circuit diagram is given below:
