Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.

The effect of current utilised in a bulb is the conversion of electrical energy into light energy through the heating of the filament inside the bulb. This process is known as resistive heating, where the current passing through the filament encounters resistance, causing it to heat up and produce light.
The filament is fine so that its electrical resistance can be quite high. It is also long, for the same reason. Usually it is coiled up to fit the length in the lamp. The heating effect of electric current is proportional to the current squared, time the resistance (I*I*R). Most of the effect is due to the current. The current through the filament must be limited to stop it melting. Adding resistance will do that. Taking resistance away increases heating. So, a low energy lamp has a very thin filament and a high energy lamp will have a thicker filament.
The filament of a light bulb allows electrical energy to be converted into radiant energy in the form of light and heat. When electricity flows through the filament, it heats up and emits light through a process called incandescence.
converted into heat and light energy.
When an electric current flows through the metal filament of a light bulb, electrical energy is converted to heat and light energy, producing the illumination that we see as light. The filament heats up due to the resistance to the current passing through it, causing it to emit visible light.
Electrical energy (the electric current) is transformed into thermal energy (by heating the filament to incandescence), and this thermal energy creates electromagnetic energy in the form of light.
Heat and light.
The electrical current that flows through the metal filament of a light bulb is in the form of electrons. As the electrons pass through the filament, they encounter resistance, which causes the filament to heat up and emit light. This process converts electrical energy into light and heat energy.
That is the result of resistance in the wire. In energy terms, some of the energy in the electric current is converted into heat.
Energy is transferred to a light bulb when an electric current flows through a filament in the bulb, heating it up and causing it to emit light. The electrical energy is converted into light and heat energy by the filament, which produces the visible light that we see.
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.

In a torch, electrical energy from the batteries is converted into light energy through a process called incandescence. The electric current passes through a filament, heating it to a high temperature and causing it to emit light.
Here are a few examples... - The electrical current is monitored. - The current of electricity is measured in volts. - The electrical current of telephone wiring is 82 volts. They may not be worded the same, but they have the same initial meaning.
In a lamp, electrical energy from the power source is converted into light and heat energy. This transformation occurs when the electric current passes through the filament inside the bulb, causing it to glow and emit light. Some of the electrical energy is also converted into heat energy, which can be felt as warmth when the lamp is on.
