How much current flows through a 60w light bulb at 120v?
The 120-Watt bulb has the lower resistance; and using Ohm’s law, one would expect it also has the higher current. In fact, the 120-Watt bulb would have a current of 1 Amp and a resistance of 120 Ω; the 60-Watt bulb would have a current of 0.5 Amp and a resistance of 240 Ω.
How many electrons pass through a lamp in 1 minute if the current is 200ma?
So no. of electrons, n = qe = 121.6×10−19 = 7.5×1019.
How many amps is 100 watts at 12 volts?
Watts and amps conversions at 120V (AC)
Power | Current | Voltage |
---|---|---|
90 watts | 7.5 amps | 12 volts |
100 watts | 8.333 amps | 12 volts |
110 watts | 9.167 amps | 12 volts |
120 watts | 10 amps | 12 volts |
Do LED lights draw less amps?
You’ll find out why LED lights draw less from your battery while providing the same amount – or even more — light than the old incandescent ones. When Dave connects incandescent bulbs to an amp meter, they draw up to 1.6 amps, but when LED lights are used, they only pull about . 26 amps.
What is the current that runs through a light bulb?
A 5.00 A current runs through a 12 gauge copper wire (diameter 2.05 mm) and through a light bulb. Copper has 8.5*10^28 free electrons per cubic metre.
How long does it take for light to travel one centimeter?
For one centimeter, light takes 3.3e-11 seconds. These are 0.000000000033 seconds (first digit ≠0 at the 11. decimal place).
How long does it take a light to reach the Moon?
Please enter distance or time, the other value will be calculated. One year is counted as 31557600 seconds (365 1/4 days). Examples: the average distance of the moon from earth is 384400 kilometers. The light takes just under 1.3 seconds to get there. For one centimeter, light takes 3.3e-11 seconds.
How do you calculate the speed of light in seconds?
Speed of light calculator for the distance per time or time per distance. distance = speed of light * time. s = c * t. Please enter distance or time, the other value will be calculated. One year is counted as 31557600 seconds (365 1/4 days).
