What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
How many volts should I be reading at a fluorescent bulb?
The voltage present on the secondary side of the ballast (transformer) varies as to the type of fluorescent tube or bulb that is in the fixture. The voltage will always be higher that the applied line voltage that supplies the ballast.If the fluorescent bulb screws into a lamp type of fixture, then there is no way to measure the voltage at the bulb as the tube and ballast are a combined sealed unit.
Can you plug a 220V light bulb into a 240V base?
Yes, you can plug a 220V light bulb into a 240V base. The slight increase in voltage should not affect the operation of the light bulb significantly, as most light bulbs have a tolerance range built-in to handle small voltage fluctuations. However, it's always a good idea to check the manufacturer's specifications for the light bulb to ensure safe operation.
What happens to the brightness of a bulb if the volts are increased?
The electrical potential energy increases as the voltage is increased. It further excites the filament in the bulb more than a lessor voltage would. Using good old ohm's law (Voltage = Current x Resistance), a larger voltage applied to a bulb at the same resistance increases the current proportionally and larger currents has the effect to cause higher temps in conductors
What happen when 3 cells of 1.5V is connected to one end of wires then connected to small torch bulb?
Nothing, for electricity to flow there has to be a voltage difference, ie connected from one end of the cells to the bulb, AND from the other terminal of the bulb to the other end of the cells.
How do you alter the brightness of a bulb?
You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
A light bulb has a resistance of 5 ohms and a maximum current of 10 A. How much voltage can be applied before the bulb will break?
50-Voltage
When a light bulb is rated for 3.2 V does that mean that is the maximum operating voltage OR the minimum operating voltage OR or the optimum operating voltage?
When a light bulb is rated for 3.2 V it means that it is the maximum operating voltage to be applied to the bulb.
How does the voltage affect the brightness of a volt light?
The brightness of a light bulb is directly proportional to the voltage applied to it. Increasing the voltage increases the brightness of the light bulb, while decreasing the voltage decreases the brightness.
How is voltage determined on a light bulb?
Voltage on a light bulb is determined by the amount of electrical potential difference applied across its terminals. The higher the voltage, the brighter the bulb will shine. Light bulbs are typically rated to operate at a specific voltage, such as 120V for standard household bulbs.
What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
Connected in series or parallel will each bulb glow brighter?
In parallel, each bulb will have full voltage applied across them. However, in series, the voltage across each bulb won't be the same as supply voltage. Thereby, bulbs connected in parallel will glow brighter.
Why do several 40watt and 220volt lamps not light to full brilliance when in series?
To get full brightness, the rated voltage has to be applied across the bulb. When several bulbs are connected in series, the voltage gets devided among these sevral bulbs and correct rated voltage will not be applied acros each bulb, hence the brightness reduces.

What voltage is required a pass 0.5 A of current through a 4.5-W bulb?
9 volts====================The question is a bit convoluted.The power dissipated by the bulb and the current through itboth depend on the voltage applied across it.In the real world, the way to ask this question would have to be:If a light bulb dissipates 4.5 W of power when 0.5 A of currentpasses through it, what voltage has been applied across it ?(And, for extra credit, what is the bulb's effective resistance ?)

However, it's always a good idea to check the manufacturer's specifications for the light bulb to ensure safe operation.
Why there is no current in a light bulb unless it is connected across a source of applied voltage?
A current is the flow of electric charge, which requires a potential difference (voltage) to drive it. In the case of a light bulb, the voltage from a source (such as a battery or outlet) is needed to create the electric field that allows the electrons to flow through the filament of the bulb, generating light and heat in the process. Without this applied voltage, there is no driving force to push the electrons through the circuit, so no current flows.
