Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.

Why is the Cable of a cooker thicker than the cable of a table light?
More electricity needed by a cooker requires a thicker cable than for a table lamp.
Principle of operation of UV lamp?
A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. A fluorescent lamp converts electrical power into useful light more efficiently than an incandescent lamp. Lower energy cost typically offsets the higher initial cost of the lamp. The lamp is more costly because it requires a ballast to regulate the flow of current through the lamp.
Why flourecent lamp are better source of light than incandescent lamp?
because fluorescent lamp consume least voltage than incondescent bulb.
Is less current out of a lamp than in?
No.
Will a egg cook faster under a blow dryer or lamp?

Can a solar panel work under a lamp?

How long can you keep a lava lamp on for?
It is not recommended to keep the lava lamp on for longer than 10 hours at a time.
Can you put a 40w bulb in a 60w lamp?
A wattage recommendation is applied to fixture after extensive testing. It is the bulbs approximation to the fixture that is the main concern. There is a certain amount of airflow around the bulb that is taken into consideration. A larger bulb is considerably hotter and this extra heat is what could damage the fixture. You should always go by the manufacturers recommendation.
Which kind a light bulb uses the least amount of energy a fluorescent lamp a halogen lamp a incandescent lamp or a heating lamp?
Fluorescent lights use far less energy than any of the others listed.
