What changes are to be made for a fluorescent lamp circuit to work if ac supply is replaced by dc?
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.

What advantages do fluorescent tubes have over incandescent bulbs?
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
What is the meaning of the coronary circuit of the heart?
It delievers the blood supply to the heart muscle itself
Will Compact Fluorescent light bulbs interfere with garage door opener receivers?
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.
What size socket to remove pickup bed bolts on a 94 ranger?
T-55 Torx Bit, unless they're been replaced before. Auto supply and hardware mega-chain stores have them.
Do incandescent light bulbs not get as hot as fluorescent light bulbs?
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
What is the function of capacitor across the supply to the fluorescent lamp when it is used?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
What is supply and temperature independent biasing?
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.
Can the supply be increased in R-L-C circuit without changing the frequency and without affecting the impedance of the circuit?
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.
What would happen if a circuit wire is replaced by a longer one?
the brightness of the bulbs would decrease because the cell would have to supply more power.
Why transformers are connected at input to any circuit?
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.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
How to figure out ampreage in a circuit?
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.
Does tube light work with ac or dc?
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.
If the power supply does not spin what should you do?

How can a transister can amplify the voltages?
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.
What causes voltage fluctuations in an electrical circuit?
Voltage fluctuations in an electrical circuit can be caused by factors such as variations in the power supply, changes in the electrical load, or issues with the wiring or connections in the circuit. These fluctuations can lead to unstable voltage levels, which may affect the performance and safety of electrical devices connected to the circuit.
Why DC supply is used in control circuit?
dc supply is used for control circuit because dc current is an independent source .
