Is light bulb one or two words?
It is two words. It is not a combination of light and bulb.
How does electric current flow in the b connection?
how does electric current flow in the b connection? do the two bulbs in a series circuit, light when the middle bulb is loose? why?
Is a light bulb a compound?
No. The light bulb is two words, not a combination of light and bulb.
Is light bulb a compound word?
No. The light bulb is two words, not a combination of light and bulb.
Is there any such thing a completely functional single component electrical devices that does not have nay electrical connections and does not need to electrical leads?
screw-in light bulb? LIGHT BULB HAVE two connections. Clamp on meter is one instrument that has no physical connection
Why must there be two connections to a batter and to a light bulb?
The electrons must go from the battery to the light-bulb, then come back again to the battery through the other connection. If there is only one connection, there will soon (within microseconds or so) be an accumulation of electrons that will repel any additional electrons - the current will stop flowing.
What forms of energy does the electric light bulb made?
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 circuit it will have electicity passing through it when the power is switched on. The bulb glows because of the filament is thinner than that of the rest of the circuit. The filament gives off heat energy and begins to glow, this glowing we call light energy. You now have two forms of energy.
How a meter would be connected in a circuit to measure the voltage at a light bulb?
"Voltage" is the difference in electrical potential between two points in a circuit.If the voltage across the light bulb is what you want, then first make sure thatthe meter in your hand is a voltmeter, and then touch each probe of the voltmeterto one of the connections on each side of the light bulb.If you want to determine whether power is getting to the light bulb, you stillhave to do it by measuring the difference in voltage between two points. Youcould use your voltmeter to measure the voltage between one connection atthe bulb and one connection at the switch. If the power is getting from theswitch to the bulb, then the voltage between the switch and the bulb shouldbe zero (or very small).The voltage between the two connections to the switch should be zero whenthe switch is ON, and mains voltage (115 or 220) when the switch is OFF, etc.I have worked alongside individuals in the past who claimed that they coulddiscern the presence of voltage, and even measure it, by licking their fingerand touching it firmly to the circuit point in question. I don't know how manyof them are still alive, and I strongly recommend AGAINST that technique.
Which is hotter a fluorescent light tube or a light bulb?
By far the hottest of the two light sources is the light bulb.
What is the problem if you have tail lights but only one brake light?
The tail light/brake light bulb has two filaments. If one of the filaments is broken, you will get either only tail lights, or brake lights. If a new bulb doesn't work, then you have a broken wire or bad connection in your plug-in.
Do you need positive and negative connection to light a bulb?
Yes. Because if two poles are the same it wont attract Always positive and negative connect they have to be different.
Will two batteries and a wire make a light bulb light?
first of all, you need a bulb, a wire, and ONE light bulb. You clip the wire on the battery and touch the wire on the bottom of the light bulb
