Best Answer

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 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.

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.


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 is a pin based fluorescent light fixture?

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.


Why DC supply is used in control circuit?

dc supply is used for control circuit because dc current is an independent source .
