Is a circuit that has two light bulbs and one battery less bright than a circuit that has two batteries and two light bulbs?

because one battery distributes an even amount of power. the only way that both of the light bulbs with two batteries will stay the same brightness is if the batteries ans light bulbs are in a parallel circuit. then the power is distributed evenly between the light bulbs. If the lighbulbs are in a simple circuit then the first lightbulb (in a positive to negative direction) will be brighter because it uses up more energy before it can get to the second light.

∙ 11y agoThere's no general answer to that question. It could go either way, depending on
the specific equipment in use. There are batteries of many different voltages, and
light bulbs of many different resistances. It also makes a difference whether the
two light bulbs are configured in series or in parallel, and whether the two batteries
are in series or in parallel.
AnswerFor a lamp to operate at its rated power, it must be subject to its rated voltage. So the answer is straightforward: whichever combination results in the lamps each receiving their full, or close to their full, rated voltage will result in them operating at their brightest.

What could you do to a closed circuit consisting of 2 batteries and 2 light bulbs and a switch too increase the current?
The switch will not increase the current. The only thing that will increase the current is adding a larger load.Another AnswerTo maximize current flow in a circuit with 2 Flashlightbatteries, 2 Flashlight bulbs, and a switch, set aside the bulbs, put the batteries in series, connect the switch between the end poles of the battery set, and close the switch. The batteries will get hot and probably leak electrolyte, and be drained in seconds.If you want to maximize current through the circuit withthe bulbs in it, connect the bulbs in parallel to each other, and in series with the switch.
Are there supposed to be light bulbs in a parallel circuit?
Yes, light bulbs can be powered by a parallel circuit.
What would happen if one of a set of light bulbs burn out in a parallel circuit?
It depends on the circuit. If it is a constant-current circuit, any light bulbs connected in parallel with it will become brighter. If it is a constant-voltage circuit like a typical household circuit, nothing will happen. Any connected in series with it will go out.
What would be different about the circuit if a resistor were added in series with the light bulbs?
The total current in the circuit will decrease.
Why are some light bulbs frosted?
To reduce the glare
Why are two bulbs in parallel bright when you build a parallel circuit with two bulbs a one d- cell battery?
Two bulbs in parallel are brighter than the same two bulbs in series, given the same potential voltage, because there is twice the available voltage to each bulb.

Can i build a electric circuit by using wire a bulb a battery?
yes! connect all the bulbs in parallel.. i.e. battery positive terminal will be tied to one side terminals of bulb and other terminal to the other. but it will result in less power delivered.. and fast battery usage..
Can a car battery light a bulb?
Most car batteries are 12 volts. They can light 12 volt bulbs. The bulbs in your house are likely 120 volt bulbs. A car battery will not light those without some very special equipment, or unless you were to wire ten car batteries in series.
How do you make a circuit with 3 bulbs 2 switches and and 2 batteries where the 1st switch controls the lighting of all the bulbs and the 2nd switch controls the lighting of the second bulb?
Connect the two batteries for the voltage needed. If they are 12 volt batteries and the lights are 12 volts, connect the batteries in parallel (negative to negative and positive to positive). If they are 12 volt batteries and the lights are 24 volts, connect the batteries in series (negative of one battery to positive of the other). Run a wire from batteries to first switch, then to two of the lights and the other switch (in parallel). From the second switch run a wire to the third light, then connect all three lights back to the battery.
What materials are needed to light a bulb in a circuit?
batteries, wire, connectors, and light bulbs
What is the best way to light up 4 mini maglite bulbs at once?
A battery or batteries at the same voltage as the rating of the bulbs. Probably hooked in parallel.
How many batteries can light up bulbs?
This question cannot be answered without knowing at least the voltage of the light bulbs and also the voltage of the battery that is being asked about.
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
Where might one go to find cheap car batteries?
Some of the cheapest car batteries can be found on many online stores. Some examples of these stores include Battery Mart, 1000 Bulbs, Rural King, and Rich battery.
What wattage does a light bulb have to be to be powered by a battery?
Reasonobaly low. maximum 7 for Ds. just fiddle around with differend bulbs and batteries unless the battery is lead-acid
What type of circuit would be used in a battery operated torch?
Torch equals flashlight. Battery negative connected to case switched to bulbs outside. Positive connected to the lamps bottom. Called a series circuit.
