AC or DC supply is given to a bulb which gives more illumination?
In AC supply, the RMS current is the effective current for power used in a resistive circuit. This is defined as the square root of the mean value of the square of the current, taken over a whole cycle. The RMS current dissipates power at the same rate as a DC current of the same value. A light bulb of course gives out light dependent on the current through the filament. So if the RMS current and the DC current are the same value, the light produced will be equal. With AC supply, the RMS value of current and volts is 1/(square root of 2) x the peak value, so peak value = 1.414 x RMS value. If you supplied DC at volts and current equal to the peak AC value, the power given to the light bulb would clearly be greater. Therefore to answer your question you have to specify what relative values your AC and DC supplies have.
When electric current is passes through a bucket full of water lot of bubbling is observed this suggests that the types of supply is?
The bubbling observed when an electric current is passed through water in a bucket suggests that the supply is direct current (DC) rather than alternating current (AC). This is because electrolysis, which causes the bubbling, occurs more effectively with DC than AC.
What does a DC Pass through splitter do?
A DC pass-through splitter allows direct current (DC) to pass through without interruption while splitting the signal to multiple devices. This is often used in situations where a single power source needs to supply power to multiple devices without affecting the flow of electricity.
How does clamper work?
A clamper circuit is an electrical circuit that shifts the DC level of a signal. It consists of a diode, capacitor, and resistor. When a positive or negative peak in the input signal is detected, the capacitor charges or discharges to shift the DC level. This allows the output signal to oscillate around the desired DC level.
What are the Differences between tesla and Edison?
Tesla and Edison had different approaches to electrical technology. Tesla focused on alternating current (AC) systems, which are more efficient for transmitting electricity over long distances. In contrast, Edison primarily worked with direct current (DC) systems. Additionally, Tesla was known for his inventive mind and theoretical work, while Edison was more of a practical inventor and focused on developing commercial products.
Can we use fluorescent lamp in dc?
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.

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 type of fluorescent lamp is commonly used in an exterior sign?
A high output lamp with a dc recessed base connected to a high output -10 degree ballast. Anything else will not work properly in cold weather.
If AC is replaced by DC in a fluorescent lamp circuit will the circuit work?
No.
Do transformers work on DC supply?
No, unless you have a pulsating DC
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 does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
Why dc source is used for dc supply?
it is only work on it so that used
Power factor of dc ballast is 0.8. what will be the power factor same ballast in AC?
Power factor is an AC only term, and has no meaning for DC.
Do pulse transformer is work on dc supply?
hthhrhr
Does an pure inductive load work in dc supply?
no
