Hello friends,
CFLs also help to reduce greenhouse gasses, other pollutants associated with electricity production, and landfill waste (because the bulbs last longer), they are clearly the environmental winner when compared to traditional incandescent light bulbs. Switching from traditional light bulbs (called incandescent) to CFLs is an effective, simple change everyone in America can make right now. Making this change will help to use less electricity at home and prevent greenhousegas emissions that lead to global climate change. Lighting accounts for close to 20 percent of the average home’s electric bill. ENERGY STAR qualified CFLs use up to 75 percent less energy (electricity) than incandescent light bulbs, last up to 10 times longer, cost little up front, and provide a quick return on investment.

Hello friends,
I would like to say, the lv fuse’s breaking capacity can be significantly increased and current-limitation achieved by means of a granular filler (usually quartz sand) embedding the fuse element. Some fuses have indicators or strikers, tripped by the recovery voltage, to indicate whether the fuse has operated and to allow for easier detection of faulted circuits.
Although the basic design of fuses has not changed much in many years, the evolving engineering methods and modern materials sciences assist to keep improving the performance of fuses.

Over the years I have seen and created a number of computer tools (e.g. Spreadsheets) for making Electrical Load Calculations, Voltage Drop Calculations and Panel Schedules.
Thanks a lot

Hey there,
Many many thanks for sharing your information,
One problem the power supply might encounter is a blackout, Lithonia
Lighting, a leading authority on sustainable and energy efficient
lighting solutions, offers the decorative fluorescent Parlor family for
residential and light commercial lighting applications. The Parlor
family's traditional elegance is realized by its classic chrome finish
and frosted white glass.Thank you

Hello there,
There will be some resistance in the semiconductor material that causes a voltage to be generated across the device. This voltage is proportional to the current through the diode. Added to this is a voltage, usually less than 1 volt, below which the diode won't conduct in the forward direction. The POWER dissipated in a diode is equal to the voltage across it multiplied by the current through it. So a conducting diode will always get warm. A 5 volt zener will regulate to (obviously) 5 volts, a 25 volt zener to 25 volts. The power rating of the zener is important since considerable power will be dissipated in this type of circuit.

Hello there,
The 10VA & 110VA are called steady state ratings. Find out the transient kVA requirement from this transformer. This will be the aggregate of the inrush VA of all the components – that are expected to be simultaneously switched ON – connected to the control transformer secondary winding. Find out transient current from: Transient kVA/Secondary Voltage. Find out the duration of this inrush current. Whatever fuse you select, find out the trip time from the I-t curve of the fuse – for this transient current. You should select such a fuse that the tripping time of the fuse for the transient current should be more than the inrush duration.
