Why is an incandescent lamp cool to the touch when it gives off heat?
An incandescent lamp is not cool to the touch unless it is an extremely low wattage. Heat given off by incandescent lamps is one of the drawbacks of the lamp. Total overall efficiency is reduced by the wasted heat.
Light frequency from an incandescent lamp depends on what?
The peak Frequency
Can you use an incandescent light bulb in a full spectrum lamp?
no
What is equal to 60 watt in CFL?
If the question is what wattage compact fluorescent (CFL) lamp has a similar light output to an incandescent lamp of a given wattage, the ratio is usually about 4. A 60W incandescent can be replaced by an 13-15 W CFL lamp. A 60W CFL lamp can replace a 300W incandescent lamp.
What is the most economical incandescent bulb 10 watts or fluorescent lamp 10 watts and why?
the most economical is the incandescent bulb because the power of bulb is low only while the fluorescent lamp is low and additional the power of ballast from 10%-20% power consumed.but the fluorescent lamp is 5 times brightly the incandescent bulb.
What can an incandescent test lamp is used to check?
An incandescent lamp can be used to check continuity of a circuit.
A choke coil placed in series with an electric lamp in an ac circuit causes the lamp to become dim why is it so?
The light is getting dim because the choke is using the energy the lamp should be using. The purpose of the choke is to remove transients; if it is using power at 50 or 60Hz, this is not desirable. My guess is this lamp is using a new energy efficient (not incandescent) light bulb? If this is the case, don't. If this is a choke you added to the lamp, then perhaps it's the wrong type choke (too large inductance). If you added this, it could be that you inadvertently inserted resistance in the lamp wire. Check to make sure nothing is getting hot around your new wiring. A bad solder point could cause this to some degree.

Is CO2 emitted by incandescent bulb?
