The total energy delivered to each bulb in a circuit depends on the voltage of the circuit and the resistance of the bulb. In a series circuit, the total voltage is divided among all bulbs, so each bulb receives less energy compared to a parallel circuit where each bulb gets the full voltage of the circuit.
What else can I help you with?
If 100 J goes into a light bulb how much energy comes out of the light bulb in total?
The amount of energy that comes out of a light bulb is typically less than the energy that goes in, due to energy losses in the form of heat and light. The efficiency of a light bulb is determined by its design and technology. The amount of useful energy output can vary depending on the type of light bulb used.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
Does the size of the light bulb affect how much energy it uses with wire and a battery?
The size of the light bulb (wattage) affects the amount of energy it consumes. A higher wattage bulb will use more energy than a lower wattage bulb with the same wire and battery. The wire and battery provide the electricity needed for the bulb to produce light.
How much energy does an 11watts bulb use per second?
An 11-watt bulb uses 11 joules of energy per second.
What does the number on the top of a light bulb indicate?
The number on the top of a light bulb indicates the wattage of the bulb, which is a measure of the amount of power the bulb consumes. This can give you an idea of how bright the light will be and how much energy it will use.
When 60 W means that W joules of energy are transferred into the bulb each second. In use how much energy is given out by the bulb each second?
The light bulb will use electrical energy at the rate of 60 W (60 J/s), and it will emit that energy, also at the rate of 60 W.Note that in any real light bulb, only part of the energy is emitted as visible light. The remainder is mainly heat.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
If you add an extra battery to a circuit containing a bulb how will this affect the bulb?
The bulb becomes brighter unless it is too much till it shot-circuits.
How much does it cost to run a 100 watt bulb per hour?
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015
How much energy do you save with 10 light bulbs off?
That depends on the power used by each light bulb. Look at the specifications for a specific light bulb, then multiply the power by 10. Note that energy = power x time; that is to say, the energy spent by a light bulb depends on its power, but also on how long you keep it on. Specifically, watts = joules x seconds.
If 100 J goes into a light bulb how much energy comes out of the light bulb in total?
The amount of energy that comes out of a light bulb is typically less than the energy that goes in, due to energy losses in the form of heat and light. The efficiency of a light bulb is determined by its design and technology. The amount of useful energy output can vary depending on the type of light bulb used.
Different color light bulb affect how much energy it has?
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
If a lamp bulb is rated at 100 watt why is a time factor not in the rating?
The wattage rating of a lamp bulb is a measure of the power it consumes, not the duration it operates for. The rating tells you how much power the bulb will use when it is in operation, but it does not provide information about how long the bulb will last before needing to be replaced.
How much energy does a 5 watt light bulb use off?
A lot
What do you need to know to calculate how much energy light bulb uses?
You should be able to read the power off the bulb or its packaging.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
How does the brightness of the bulbs in the two circuits compare?
ANSWERwhen two bulb are connected in series their will not be any changeANSWERWhat other bulbs? This question doesn't make sense.Perhaps you are thinking of this: with two bulbs in series, each bulb only gets 1/2 of the energy (or voltage) that a battery makes available, so each bulb is much dimmer than just one bulb attached to the battery would be.
