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.
current flows and we have light from bulb....
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.
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.
when a light bulb is switched on it will blown..............
Energy is transferred from the battery to the bulb of a torch or flashlight through a closed circuit. When the battery is connected to the bulb, it provides electrical energy to the filament in the bulb, which then converts the electrical energy into light energy through the process of electrical resistance. This light energy is what produces the glow in the bulb.
you can make a torch bulb
No, a tomato cannot glow when connected to a light bulb. Tomatoes do not have the ability to produce light on their own, so they cannot glow like a light bulb.
The job of a bulb is to give off heat and light energy
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
you have to need IC 3 ,bulb
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
