Why the bulb does not light up in a closed circuit?
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
No the circuit needs to be closed for this.
Closed. Think of the switch as being a gap in the circuit. If you close the gap the light lights.
It will light up in a complete circuit if the switch is closed but if the switch if open the energy will not completely pass because it is open
Well, i have a little knowledge in electricity so I'll share with you the little that i know and i hope it will answer your question. When another light bulb is added to a circuit, the electricity is shared throughout the circuit and therefore both the light bulbs will light up. There will be little or no impact to the first light bulb. That is both for an open or a closed circuit. If though… Read More
If that branch of the circuit has enough current it will light up.
*Look at the simple circuit illustrated in Figure A-2. What will happen when only switch S1 is closed? Correct Answer= "Nothing will happen-the light bulb won't light up." <<>> If there is a load in the circuit the load will operate. If there is no load in the circuit and it is complete then a short circuit will occur and something in the circuit will burn open. If the circuit is complete and there is… Read More
It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.
It is a load that gives off light when current heats up filament in an incandescent bulb.
If you wired up the circuit with a bulb two batteries and a switch with a thin wire what will happen?
the bulb will light up
What happens when a switch connected to an electric circuit that is meant to make a bulb light up in the off position explain why?
I think the bulb will light up
light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .
To make a light bulb fainter use more light bulbs in the circuit so the power is shared or use less power as then there wont be as much energy to light up the bulb.
In a balanced condition of a bridge circuit a bulb was placed instead of galvanometer will the bulb light up?
No, It will go out.
To provide electricity for the bulb to light up.
Using a remote control similar to those ones used to turn on electronic devices. The infrared rays can switch the light bulb on, since it has a small transistorised circuit that can actuate a tiny relay to put the light bulb in series with the electric circuit.
In a series circuit, all bulbs are necessary to complete the circuit. If one bulb goes out, the circuit is broken, so none of the bulbs would light up.
How can you use a wire battery and a light bulb to test an item to see if it is a conductor of electricity?
If the object is conductive, when added to a circuit containing a light bulb and a battery, connected by wire, the light bulb will light up. Depending on how good a conductor the object is, the brighter the light bulb will be.
If it is a 1.5 volt bulb you can connect it through a series circuit directly to your battery. If the bulb is not made to run on 1.5 volts and needs another voltage, it may not light up!
First answer: No. Second answer: Yes. A light bulb is a resistance. Current flows across a tungsten filament, heating it to produce light. However, if there was some other resistance wired into a closed circuit, a screw type bulb could be used as a switch. You unscrew it to throw open the circuit, effectively turning off whatever else was wired in the line. Screw it back in to switch it on. So yes, you could… Read More
The job of a battery is to power the torch. if the circuit is not complete then the bulb wont light up and if the batteries arent the right way round the bulb wont light up either.
The element (filament) in the bulb passes electricity but has a certain resistance - pushback. It's this pushback that makes the filament grow hot with the current flowing through it from the circuit and when the filament is hot enough it produces light. The electric circuit is there to prove the current flow which heats the element and produces light.
it either blows up or worn out
If you want to physically do it, connect up a simple circuit with wires, a battery and a small bulb. Put the object in the circuit (touching the wires) - if the bulb light, its a conductor.
A switch completes the circuit, allowing electricity to pass from the cell (battery) to the bulb.
How do you connect the parts of a simple electric circuit together so that the light bulb lights up?
Simply connect the -ve of the bulb to -ve of the battery and +ve of bulb to +ve of battery using an electrically conductive wire, the bulb will light automatically.
it m eans that either a bulb has blown or there is a fault on the lighting circuit
1. Battery 2. Wires 3. light bulb, buzzer
What needs to be complete is the circuit from the battery to the bulb, then the other wire from the bulb to the other side of the battery. If it is from an outlet rather than a battery, the circuit starts and finishes with the live and neutral pins at the outlet.
What happens when you put an electric motor with higher resistance and a light bulb with less resistance in a series circuit. does the bulb light up and motor spin. or only the motor spin?
(Another possibility is: Bulb lights up and motor does not spin.) The result all depends on the relative resistance of the bulb and the motor, because that determines how much of the supply voltage appears across the light bulb, and how much across the motor. That's one of the big problems with a series circuit: The performance of one device depends on the characteristics of the other devices in the same circuit. If you turn… Read More
Electricity can flow in an electric circuit by a battery. The battery creates electrons, which flow through the wire, and then go into a light bulb. (That is how a light bulb in a circuit lights up.) A series circuit is a circuit with one wire that electrons can flow through. Also, there can be more than one light bulb connecting to the same wire. A parallel circuit is a circuit with light bulbs that… Read More
If we're talking about in-circuit diagnostics and measurements with the device powered on (like it oftentimes is with TV sets, or at least used to be), the light bulb serves a dual purpose: a) the bulb acts as a huge resistor capable of dissipating (as light) great quantities of power (unlike typical resistors which go up to say, 7W, a light bulb could be even 100W) - thereby protecting critical components from burning b) the… Read More
Think of this as two scenarios. First, we have one blub, one battery, and two wires in a closed circuit, and the bulb lights up. Next, think about what would happen if we added a couple more wires to the circuit. The bulb would still light up, just as brightly, meaning that the new wires are not increasing the amount of resistance. This means that the wires are not slowing down the flow of charges.
A parallel circuit lights up even when one bulb is out.
If you connect the circuit properly the bulb should light up. That means attaching the left side of the battery to the right side of the bulb using a wire and attaching the right side of the battery to the left side of the bulb. If you do that the your bulb should turn on. If it doesn't then try changing the battery or the bulb.
when you have two batteries, and are linked together according to how the signs are, the electrical communication occurs and if the switch is open it doesn't light up the bulb, but if closed, it lights up the bulb.
The most likely reason is that the over current has burned the bulb filament open.
If something is fused, then it no longer makes an electrical circuit and therfore no longer works,
It doesn't. If you are testing this with a test light, you are completing the circuit through the bulb and that makes the filament light up.
an electric circuit consists of a voltage source (like a battery), something to use up some of the voltage to keep it from short circuiting ( like a light bulb or a motor), and wires to connect the positive end of the battery to the light bulb or other device, then more wire to connect the other part of the bulb to the negative end of the battery.
First let us understand the different parts that go to make up the light bulb shall we? The key component in a light bulb is the filament, this filament, ususually a thin piece of wire, is connected to two contact points. These points are then connected to the metal base of the bulb. When the bulb is attached to the light socket a circuit is then made. As the thin wire is part of the… Read More
Maybe the most common example of a series circuit in the home is a switch and the light that it turns on and off. When the switch is closed so that the light is on, electric current flows from the main house panel through the line wire (usually black) to the switch, through the switch, and on to the light fixture (still in a black wire). At the light fixture the current runs into the… Read More
To get an open circuit to work and light a light bulb, turn the switch on. Or hardwire it to power up the lamp. If the battey or other power source is good, and so is the lamp, make sure all the connections are good and that the conductor (wire) isn't broken. With all the components in good shape and properly connected, the light should be glowing.
Yes. Each light bulb is just another resistor in a series circuit, where you add the individual resistances to get the total resistance (unless the bulbs are set up in parallel, where adding a second identical light bulb would cut the total resistance in half).
A bulb lights up because the power dissipated by the filament is high enough for it to get hot and glow. After all, that power has to go somewhere, so why not via transfer of radiant energy????
Strings of Christmas lights were made of miniature lamps connected in series if one lamp is removed what would happen?
all the lights would go out which is why most new lights these days are wired in parallel or prevent that from happening and then you just replace the one bulb... some lights have both a series and parallel circuit in a complete light circuit. for example (A) the complete light circuit has 4 (B) series sections and with each series circuit you have a (C) parallel circuit... so when (A) is lit up and… Read More
A: It does not mater how it is connected a bulb will light up the same if the same power is available.
The switch closes the circuit so a voltage is applied across the filament of a bulb causing current to flow heating the filament and causing it to glow.
Breakers don't blow, they trip. Do you mean a fuse? If you are talking about a breaker, you can reset it. Wether it was a breaker tripping or a fuse blowing from installing a new bulb, if the light switch was on when you installed the bulb you got an initial surge from the immediate completion of the circuit. The only thing to be cautious about is a possible fault in the light bulb base… Read More
The circuit could be faulty; the bulb could be used; and you may even have no power on!
it speeds up to let you know there is a bulb burned out or the circuit board is fried in the tail light lens
