when a light bulb is switched on it will blown..............
current flows and we have light from bulb....
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
60 Watts is the amount of electrical power the bulb uses when it is switched on.
no
When a torch is switched on, the electrical energy from the battery is converted to light energy and heat energy. The electrical energy powers the light source (such as LEDs or a bulb) to produce light, and a small portion of the energy is also dissipated as heat.
Light energy is stored in a bulb when it is switched off. When the bulb is turned on, electrical energy is converted into light energy and heat.
Potential energy, maybe?
When a torch is switched on, the electrical energy stored in the battery is converted into light and heat energy by the bulb. The electrical energy flows through the circuit and causes the bulb’s filament to heat up, emitting light as a result of this process.
the information is lost after power is switched off.
The light emitted by the bulb overwhelms our eyes' ability to perceive its physical structure, making it difficult for us to see the bulb itself when it is switched on. Our eyes are more sensitive to the brightness of the light produced rather than the object emitting it.
If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.
If your torch has an incandescent bulb in it, the resistance of the wire in the bulb generates enough heat that light is created. If your torch has an LED bulb, the PN junction in the diode creates light when the diode is forward-biased.
