Current drawn is load dependant. However load or watt is product of voltage and current. For a given load if the voltage is lower, it would draw a higher current and draw lower current if voltage were higher. Use the simple formula of power P = V * I (voltage V Current I)

AnswerA 100-W lamp has a lower operating resistance than a 40-W lamp. Since power is equal to the voltage squared divided by the resistance, for a given voltage the power will be higher and its operating temperature (therefore brightness) will be higher.

Wiki User
∙ 11y agoThe current is the ratio of the power consumption P and the voltage V:
I = P/V
The voltage is constant, so raising the power consumption to 100W draws more current.

What happens in a series circuit with three different watt bulb's which bulb will brighter?
The 2 bulb series circuit , a 3 bulb series circuit will increase resistance and therefore reduce the voltage across the bulb. The current in all points of the circuit will remain the same according to Kirchhoff.
You are using a bulb whose filament is broken will the bulb glow when connected to battery give reason?
no. it cant make its connection so it wont make any light.
Which glows more brighter a 100 w bulb or a 75 w bulb explain?
A 100 watt bulb will normally glow brighter than a 50 watt bulb as long as you are comparing similar style bulbs. You have to compare Incandescents to Incandescents, Fluorescent to Fluorescent, LED to LED, and so forth. You also have to make sure your bulbs are similar in light patterns since you can have general dispersion lighting, spot lighting, flood lighting, and so forth. So, once again as long as you are comparing like style bulbs, yes a 100 watt bulb is brighter than a 50 watt bulb.
What will cause magnesium to glow brighter?
Increasing the temperature of magnesium will cause it to glow brighter. Heating magnesium to a high temperature excites the electrons in the atoms, causing them to jump to higher energy levels. As the electrons return to their lower energy levels, they release energy in the form of light, resulting in a brighter glow.
Can you use a 5 watt bulb in a 4 watt light?
If the socket threads of the lamp are the same then yes the bulbs can be interchanged. The 5 watt bulb will glow brighter than the 4 watt bulb. If by a 4 watt light you mean a 4 watt fixture, then it is not recommended to place a larger wattage lamp in a fixture that is rated by the manufacturer at a specific operating wattage
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.
A 40W bulb or a 60W bulb will glow more brighter if connected in series?
The 40-W lamp will be the brighter, because it has a greater resistance that the 60-W lamp and, therefore, will experience a greater voltage drop across its terminals. The closer the voltage drop is to the lamp's rated voltage, the brighter it will be.
Can a tomato glow when connected to a light bulb?
no
Which bulb will glow at first when 3 bulbs are connected in series and switch is connected after 1 bulb?
All the three would glow at the same instant.
Are bulbs brighter in a series or parallel curcuit?
Batteries in series makes the voltage additive. If the bulb is only rated at a specific voltage and you double the voltage the bulb will glow brighter but its life span will be shortened. Batteries in parallel will keep the voltage at the same level as a single battery but the endurance drain of the batteries will be doubled. Example, if a battery is drained of power, with a bulb being left on continuously, in one hour then two batteries in parallel would allow the bulb to glow for two hours before the batteries were drained of power.
Did the light bulb light up when the dry cells were connected in parallel?
If dry cells are connected in parallel, they will supply more current to the bulb, which will cause it to glow for a longer period of time, but at the same brightness as if only a single cell were used. When the cells are connected in series, the voltage is increased, which will cause the bulb to burn more brightly. If the voltage is increased past the safe point for the bulb, its life will be shortened and it may burn out rapidly. In series, the voltages add. In parallel, you essentially have a larger cell of the same type (cell as in battery of one).
Why do two incandescent light bulbs glow with different intensities when connected in the same circuit?
When you are wiring two light bulbs in SERIES, you split the voltage to each light bulb in HALF, meaning that it will only glow half the brightness per bulb, but it will only draw the current of one bulb, meaning if the bulbs were connected to a battery, it would last longer to connect them together in series, rather than parallel.
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
Why are street lights connected in parallel?
street lights are connected in parallel mostly because if any lamp stops glowing but the other lamps continue their glow
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
What happens in a series circuit with three different watt bulb's which bulb will brighter?

If you have 2 5-watt bulbs connected in series and then in parallel which circuit arrangement will give you brighter bulbs?
It depends on the voltage rating of each lamp, and the value of the supply voltage. It's important to understand that a lamp will only operate at its rated power (therefore at its full brightness) when subject to its rated voltage.So, let's assume each lamp is rated at, say, 24 V.If connected in parallel across a 24-V supply, then they will both operate of full brightness.If connected in series across the same 24-V supply, then each lamp will be subject to half its rated voltage, and will be very dim.On the other hand, if connected in series across a 48-V supply, then they will each be subject to 24 V, and will both operate at full brightness.
