An electric lamp has a resistance of 534 ohms when connected to a 230v supply the current flowing would be?
I = E/R
What happens to the ammeter reading when a lamp is added to a circuit which contains two cells and a lamp in series?
Assuming the new lamp is in series, the ammeter reading falls because the total resistance has increased. By how much depends on how the lamp resistance depends on voltage. If the lamp is added in parallel to the first, then the ammeter reading doubles.
Would the amount of light increase decrease or remain the same when lamp is placed across a 120 V dc power line?
When a lamp is connected to a power supply the total amount of light increases.
How does the number of bulbs affect the amount of electrisaty in a circuit?
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.
What happens to the voltage of a series circuit as you add bulbs to the circuit?
For any lamp to operate at its rated power, it must be subject to its rated voltage. If you connect, say, three identical 120-V rated lamps across a 120-V supply, then each lamp will be subject to one-third of its rated voltage. As a result each lamp will not be able to achieve its rated power. If the lamps have different power ratings, then it is rather more complicated, with the most powerful lamp becoming the dimmest while the least powerful lamp becoming the brightest.
Covering a lighting spirit lamp with a lid what happens?
It cuts off the oxygen supply to the spirit lamp and lamp goes off.
What does CFL's in lighting stand for?
The fulform of CFL bulbs is compact fluorecent light
How do you say the lamp in Everything but nouns replaced with dinosaur?
dinosaur lamp
Why does the lamp bright when connected to the AC?
why does the lamp bright when it is connected to the AC supply
What happens to a voltage as the Christmas lights are connected in series?
Divide the number of lamps into the value of the supply voltage, and that will tell you the voltage drop appearing across each lamp. Bear in mind that if one of the lamps should be removed, the full supply voltage will then appear across the empty lamp holder.
Will a 240 volt lamp work in a 110 volt supply if the supply fuse size were increased?
No. The 240V lamp will pop the circuit or fuse because the draw is higher than the supply.
What is the function of capacitor across the supply to the fluorescent lamp when it is used?
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
What happens if you put a lava lamp in the microwave?
The lamp will explode.
What happens to the current in a circuit if more lights are added?
Assuming you are referring to house lamps, these are always connected in parallel with each other. Each lamp will draw a current, the value of which depends on the wattage of the lamps. As each lamp is added, the supply current will increase by the amount of current drawn by that lamp.
If the brake lamp light is on a 98 Honda Accord what does that mean?
On a 1994 Honda Accord, the brake lamp comes on when a tail light is no longer working. The burned-out bulb needs to be replaced. The brake lamp will not come on after the bulb is replaced.
Why would I need a lamp for my LCD TV?
The lamp is a piece of equipment that is built into your LCD TV. This lamp is what brightens the screen on the television. The bulbs for this lamp can break and need to be replaced.
