Energy flowing through the filament. In a traditional incandescent bulb most of the energy is radiated as heat which is why they are viewed as inefficient.
A closed switch completes the electrical circuit, allowing current to flow through the light bulb and generate light. If the switch is not closed, there is an open circuit, meaning the current cannot flow and the light bulb does not turn on.
a closed circuit
In a simple circuit with a battery and a light bulb, the battery provides electrical energy that flows through the wires to the light bulb. The electrical energy causes the filament in the light bulb to heat up and emit light. This process continues as long as the circuit remains closed and the battery has power.
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
In a closed circuit, electrical current flows from the power source through the wires, through the bulb, and back to the power source. When the current reaches the filament inside the bulb, it heats up and emits light, causing the bulb to light up.
The light bulb in the circuit turns on due to the flow of electric current, which is facilitated by a closed circuit. When the switch is closed, it completes the circuit, allowing electrons to move from the power source through the bulb, causing it to emit light. The resistance in the bulb converts electrical energy into light and heat, resulting in illumination.
It depend on where the switch is located in the circuit.
It is a closed circuit if there is a load in the circuit (light bulb etc), otherwise it is a short circuit (+ to - on a car battery with a screwdriver)
To make a light bulb light up, you need a closed electrical circuit. This circuit typically consists of a power source (such as a battery or outlet), wires to carry the electricity, and the light bulb itself. When the circuit is complete and electricity flows through the bulb, it will produce light.
It will not work because it has to be closed so the electricity can go to the bulb.
For a circuit to light a bulb, there must be a closed loop for the flow of electricity. This loop typically consists of a power source (e.g. battery), wires, a switch, and the bulb. When the switch is closed, the circuit is complete and electricity can flow through the wires to the bulb, causing it to light up.
There must be a current through the bulb in order for it to glow.
