Given: Power P = 100 W.
Reference power Po = 10^−3 W = 1 mW.
Reference power level LPo = 0 dB.
Get power P when entering power level LP:
P = Po×10^(LI/10) W = 10^−3×10^(LP/10) W.
Get power level LI in dB when entering power P in W.
LP = 10×log (P / Po) dB = 10×log (P / 10^−3) = 50 dB.
The reference power may be different, then the power level will be different.

How many watts does 100 amps at 120 v?
To calculate the watts, you can use the formula: Watts = Amps x Volts. In this case, 100 amps x 120 volts equals 12,000 watts.
How many ac amps is a 1500 watts?
To convert watts to amps, you can use the formula: Amps = Watts / Volts. Assuming a standard voltage of 120V, 1500 watts would be equivalent to 12.5 amps (1500 watts / 120 volts = 12.5 amps).
How many amps does a double 100 watt spotlight use?
If each spotlight is rated at 100 watts, together they would use 200 watts. To convert watts to amps, you can use the formula: Amps = Watts / Volts. Assuming a standard voltage of 120V in a household setting, the double 100 watt spotlight would use approximately 1.67 amps.
How many ampere in 240 volt with 100 watts bulb?
To calculate the amperage, you can use the formula: Amperes = Watts / Volts. So for a 100-watt bulb connected to a 240-volt source, the amperage would be 0.42 Amps.
100 watt is equal to how many va?
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
How many how many amps in 100 watts?
A three wire home distribution service rated at 100 amps has a wattage capacity of;From L1 to L2 at 240 volts x 100 amps = 24000 watts or 24 kilowatts. From L1 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts. From L2 to neutral at 120 volts x 100 amps = 12000 watts or 12 kilowatts.

How many amps does it takes to light up a led 100 watt?
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
How many kw does it take to make 100 amps?
If the 100 amps is powered by 10 volts, you have 1 kw, or 1000 watts. watts = volts X current The 'k' simply means kilo, or thousand.
1400watts equals how many amps?
Watts=Volts times Amps So without knowing the voltage the amps can be anything. At 100 Volts it'd be 14 Amps.
What is the formula for finding out how many amps is required to achieve the full 100 watt output from a 9 volt bulb?
The formula is volts times amps equals watts, or watts divided by volts equals amps.
How do you compute the 2000 watts in 220 volt to how many amps?
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
How many Watts are in 730 amps?
There are zero watts in 730 amps. Watts is the product of amps times volts. As you can see without a voltage no answer can be given.
