A fluorescent light fixture is designed to operate on an AC voltage supply. To have the fixture operate off of a DC supply a power inverter would have to be installed. The power inverter would then change the DC to AC for the fixture to operate. These power inverters are reasonably priced these days and can be bought at most DIY stores.
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
It delievers the blood supply to the heart muscle itself
AnswerThey shouldn't; that kind of thing is checked and regulated by the FCC. However, a CFL has a high frequency switching power supply in it, so it is possible. My garage door opener would not open or close until the the compact fluorescent light bulb timed out. There is a warning on the CFB that says that it can interfere with electronic circuits and it does.
No, given the same lumen rating. Florescent lights are more electrically efficient than incandescent bulbs. Be careful, fluorescent bulbs currently contain mercury and should be handled and disposed of properly. For more information, you may also want to read. http://home.howstuffworks.com/question236.htm
LED means light emitting diode. Diode is an electronic component which has two nodes. when power supply is given between two nodes the current flows and emits light from it which is in visible spectrum. Hence light appears from LED lamp. As the energy required for emitting light is very less hence LED lights give very high lumens per watt

The signal or output of a circuit is often affected by changes in the supply voltage and/or ambient temperature. A biasing circuit is designed to consistently output a selected voltage (or current). Depending on the circuit topology, a change in supply voltage or temperature can cause the intended value to drift. In an increase in temperature can, for example, increase resistances in a circuit. Such effects are usually undesireable and thus a supply/temperature independent bias would be needed. Electronic component manufactures will frequently provide tolerances for outputs relative to changes in supply voltage and temperature.
Neither the frequency nor the impedance of the R-L-C circuit depends on the supply. Both numbers are there and can be calculated before the circuit is ever brought near a supply. They're completely determined by the values of R, L, and C, and they don't change even if the supply changes.
the brightness of the bulbs would decrease because the cell would have to supply more power.
to give required power supply to circuit A: . 1] changes input power to a suitable power level. 2] isolate the source from the following circuitry.
ac supply is given and then in the circuit rectifier converts ac to dc
For a d.c. circuit, you divide its supply voltage by the resistance of its load. For an a.c. circuit, you divide its supply voltage by the impedance of its load.
Fluorescent lights work just fine on DC voltage, BUT one needs a current limited power source to stabilize the circuit against the negative resistance of the gas discharge. This can be done with either a resistor or an electronic circuit. The resistor solution is too lossy because excess voltage from the dc csupply has to be converted to heat across the resistor. Electronic switching supplies could supply a fluorescent light with a dc voltage and current without the losses. But that's technological overkill and most circuits still supply AC.
When it's assembled into a circuit with other components and a power supply, atransistor can be used to amplify changes in voltage, but it can't amplify voltages.
A pin based fluorescent light fixture is the type of fixture that takes fluorescent tubes. On each end of the fluorescent tubes there are contact pins. These pins are used to hold the tube in the fixture and to supply the voltage to the tube from the fixture's ballast.
dc supply is used for control circuit because dc current is an independent source .
