Since resistance is inversely proportional to the cross-sectional area of a wire, thicker the wire - lesser the resistance and vice-versa.
Now, according to Joule's law of heating,
H = I^2 R t; i.e. H (Heat) is directly proportional to the square of I (Current), R(Resistance) and t (time).
Whereas, according to Ohm's law,
V=IR; i.e. V (Potential difference) is directly proportional to I (Current) and R (Resistance)
Comparing both the formulas, we can conclude that H (Heat) needs more Current; I. [H=I^2 R t] Therefore, thicker wire.
Hence, the cooker needs a thicker wire while a table light needs a comparatively thinner wire.
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
No, an example of an electric current would be using a battery to light a lightbulb.
A ceiling rose is the name given to an enclosed terminal block which enables a suspended lamp to be connected to a residence's permanent wiring. It also provides a means of gripping the flexible cable to support the weight of the light fitting.

Installing a wall scone with an electric light can be an easy process. First the power must be turned off to prevent electric shock. Then a hole should be cut to fit the fixture and expose the wires. Match up the correct wires to the light then place the sconce in the wall. Secure the sconce with glue or nails and test the light connections.
More electricity needed by a cooker requires a thicker cable than for a table lamp.
In an electric cooker, electrical energy is transferred into heat energy through resistance in the heating element. The electrical current passing through the element encounters resistance, which generates heat as a byproduct. This heat energy is then used for cooking food.
Safest way if you don't know much about electrics is to have it checked by a tradesman, if you do know about electrics, then turn off the power to the sockets/power outlets and check where the cable comes from the wall to check if the earth wire is connected and then do the same with the back of the cooker where the wires connect, if the cooker is pre-wired (where the wire is direct into the cooker) then you would need an engineer to dismantle the unit to check. If the electric is just to power the spark and a light then it maybe on a regular power outlet with a plug. If you suspect a fault then it is best to have it checked by a qualified tradesman.
The visible and ultraviolet parts of sunlight are mainly responsible for making a solar cooker hot. These wavelengths are absorbed by the material of the cooker, which converts the light into heat energy, thereby heating up the interior of the cooker.

Concave lens. Concave lenses are thinner in the middle and thicker at the edges, causing light rays to diverge. Convex lenses are thicker in the middle and thinner at the edges, causing light rays to converge.
Eyeglasses refract light to correct for problems with the eyes. As the light needs to be bent more, the glass needs to be thicker to make the light bend farther.

Electric Light Orchestra was created in 1970.
Electric Light Orchestra ended in 2001.
