What else can I help you with?
Can you substitute a regular light bulb for a krypton light bulb?
Generally, yes. It will all depend on the voltage and the current capabilities of the supply. Mostly in torches (flashlights), you can. Using a krypton bulb wil be brighter but draw more current, reducing the life of the batteries.
Is current greater in electric iron or in bulb?
A running iron uses the same power as nine 100 watt bulbs.In the home, depending upon where you live, the service voltage is fixed at either 110 or 220 volts. Various appliances and devices require different amounts of energy, of course. Since the voltage (or pressure of delivery) is the same, the current (volume of delivery) is what changes.In round numbers, a clothes iron might draw 10 amperes of current at 110 volts, or 1100 watts of power. A light bulb might draw 1 ampere of current at the same voltage.It's easy to see that the iron will draw far more current than even an inefficient incandescent light bulb.
What does amps do in a light bulb?
Take the wattage of the bulb and divide that by the voltage of the bulb. This will give the current the bulb draws. Amps are a measure of charge (electron) at an instant of time through a conductor. In an incandescent bulb the filament is heated by the current and the characteristics of the filament, usually tungsten, is that it gives off light when heated.
What consumes more power a light bulb or toaster?
A toaster typically consumes more power than a light bulb because it requires more energy to generate heat for toasting bread. A typical toaster can consume around 800-1500 watts, while a standard incandescent light bulb typically uses about 60 watts.
Compare and contrast a 60 watt and 100 watt light bulb?
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)

Does a light bulb get brighter when the current increases?
Yes, a light bulb gets brighter when the current flowing through it increases. This is because the increase in current results in more energy being converted into light and heat by the filament in the bulb, causing it to glow more brightly.

Why does adding more batteries to a circuit cause an attached light bulb to become brighter?
Adding more batteries increases the voltage across the circuit, which results in a higher current flowing through the light bulb. The increased current generates more heat and light in the bulb, making it appear brighter.
How does a change in the size of the current through a bulb affect it's light output?
An increase in the current through a bulb will increase its light output because more current means more electrons passing through the filament, which generates more heat and light. Conversely, a decrease in current will result in lower light output as there are fewer electrons flowing through the filament to produce light.
Why do light bulbs get brighter when you attach more batteries to it?
When you attach more batteries to a light bulb, it increases the voltage across the bulb, which leads to a higher current flowing through it. The increase in current causes the filament in the bulb to heat up more, resulting in increased brightness.
If there are more wires does the light get brighter?
No. Or at least not perceptually. The wires only supply electricity to the bulb - the bulb is what limits the current.
Which 12 volt bulb will draw the most current when connected to a 12 volt battery?
The bulb with the lowest resistance. Current = Volts / Resistance
Which will generate more light on a light bulb a potato or a lemon?
A lemon would generate more light on a light bulb due to its higher acid content, which can create a small electrical current when connected in a circuit with a light bulb. Potatoes have lower acidity and will generate less energy in comparison.
What does amps do in a light bulb?
Take the wattage of the bulb and divide that by the voltage of the bulb. This will give the current the bulb draws. Amps are a measure of charge (electron) at an instant of time through a conductor. In an incandescent bulb the filament is heated by the current and the characteristics of the filament, usually tungsten, is that it gives off light when heated.
Does more current flow into a light bulb than out of it?
No. Although there is a voltage drop across the filament of an incandescent light bulb, the amount of current flowing out is identical to what flows in: current in = current out. That is an important fact to always keep in mind when solving simple electrical circuits: the sum of the currents flowing into a node equals the sum of the currents flowing out of it.
Which circuit was the light bulb the dimmest?
The light bulb was likely the dimmest in the circuit where it had the highest resistance, creating more opposition to the flow of current, resulting in less brightness.
