How many kids with add does it take to change a light bulb?

How are light bulbs efficiency increased?
The brightness of a standard bulb is directly proportional to the amount of voltage drop across the bulb itself. Thus, to increase the brightness :-Pass more current across the bulb by reducing the resistance of the circuitIncrease the voltage across the bulb, or the circuit. Change the supply.
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.
What will happen to the resistance and the brightness if you add a light bulb to the circuit?
If a rheostat is connected in parallel with a light bulb, the setting of the rheostat should have no effect on the performance of the light bulb, as long as the power supply is able to maintain its output voltage and deliver the current demanded by their parallel combination.
How is adding a ammeter to a circuit different from adding a light bulb?
When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit.
What is the current in the circuit contains two 1.5 volt batteries and 6 ohm light bulb?
If the two batteries are in series, add the voltages. Then use Ohm's Law to calculate the current (that is, divide the voltage by the resistance).
Can the current in a electrical circuit be increased by bulbs?
Yes. In normal house wiring, every time you plug in any lamp or appliance, you will increase the amount of current ("amperes" or just "amps") that you draw. The circuit breakers or fuses in your house's electrical box are there to keep you from plugging so many things in that the wire gets hot enough to cause a fire. Just to be clear however, the light bulbs do not create current. They pull current through themselves. Bulbs (and all other electrical devices) pull electrical current in the same way that opening the water valve on your sink pulls a flow of current of water. Your house's electrical service can be thought of as a water hose with the end plugged up. Whenever you let a little of the water flow out (i.e. ... turn on a light bulb) you create a current of water (an electrical current in the case of our light bulb).
In a light circuit with a constant voltage what is the effect on the current if the light bulb is doubled?
If you add one extra bulb and the voltage remains constant, then you have doubled the current drained from the regulator. 12 Volt and One 12 Watt lightbulb drains 1 Ampere Current. 12 Volt and Two 12 Watt light bulbs drains 2 Ampere Current. However: If having a 24 volt powersource and you add two 12 Volt 12 Watt in serial, then you still only drain 1 Ampere Current. NOTE: Wattage and Voltage of bulbs may be different even if the sockets are the same. Lower voltage on the bulb will increase the current drain, if voltage is a lot lower it might cause the circuit delivering voltage to burn out or blow a fuse. It can also quickly burn the bulb, sometimes in a fraction of a second. It will however do little damage to add a bulb with higher voltage than the circuit is designed for. You will then only observe that you do not get the light you might hope for. Total Current/Ampere= Combined Wattage divided by Voltage Total Wattage = Combined Current or Ampere multiplied by Voltage. Regards.
What would happen if one light bulb goes out in a parallel circuit?
Making the important assumption that each bulb is equal in electrical resistance, the current will increase proportionally to the number of bulbs added (until the current limit of the battery is reached, that is). Clarification ... The current through the bulbs that were already there doesn't change, but the newcomer-bulbs add to the total current from the battery or power supply.
How do you experiment an energy drink?
Depends which kind. If it has Electrolytes you can add a small light bulb to a controlled amount of the drink. The light bulb should light up, at least dimly.
When you add another light bulb to a circuit does it effect the voltage?
When a bulb is added in parallel to a circuit with a single bulb, the resistance of the circuit decreases. This is because the existing bulb's operating point remains the same, due to the fact that Kirchoff's voltage law states that the signed voltages around a series circuit must add up to zero, with the two bulbs being their own series circuit. A consequence of this is that the voltage across both bulbs must be the same, i.e. that the voltage across the first bulb does not change. The second result of adding the bulb is that the current in the overall circuit increases. This is because the second bulb must pull some current in order to operate, yet we know that the voltage across the first bulb did not change. As a result, due to Ohm's law, the current through the first bulb did not change. And, finally, since Kirchoff's current law states that the signed sum of the currents entering a node is zero, the addition of a second load in parallel with the first load must, therefore, represent additional current.
how to use circuit in sentence?
to complete the circuit you have to add 1 light bulb.
