What else can I help you with?
What is the electrical power of a toaster that uses a current of 15 A and a voltage of 120 V?
Multiplying 15 amps x 120 volts gives you 1800 watts, or the power consumed by the toaster
Why does an electric iron have a resistance of 15 ohms?
I never measured the resistance of an electric iron, but: the 15 ohm resistance is probably required to develop a required 806 watts of power. Using Ohm's law, I(current) = E(voltage)/R(resistance), therefore I(current) =110 volts/15 ohms = 7.33 Amps (current), and, Power (watts) = E(voltage) X I(current); 110 volts X 7.33 amps = 806 watts. The iron requires that wattage to develop enough heat in the sole of the iron. Hope this helps.
An electric clothes dryer has a resistance of 8 ohms It draws 30 A of current What is the voltage in volts of the wall outlet that it is plugged into?
Power (Watts) = Current (Amps) * VoltagePower = 22Amps * 240 VoltsPower = 5,280 Watts5280
Calculate the power out put of an amplifier that has an input of 15 μw and a gain of 25dB?
If you want to work in watts, convert 25dB to a scalling factor: 3dB = 2 x input 10dB = 10 x input 20dB = 100 x input ...25dB = 10 ^ (25/10) = 316.2 x input So the output is 15 micro Watts x 316.2 = (4700)/(10^6) = 4.7 milli watts If you want to work in dB, then convert 15 micro watts to dB: 10 * log |P| = dB = 10*log |15 x 10^6| = -48.2dB ***When you have very small (ie negative) dB, it is often referred to in dBm, or 1/1000 of dB ( 30 dBm = 0 dB) so the output is -18.2dBm + 25 = 6.8dBm, or -23.2dB
Will 1500 watts work on 220 volts?
Using the formula I = W/E, the current of the circuit will be 6.8 amps. As long as the wire is at least a #14 and is protected by a 15 amp two pole breaker There will be no problem. Just make sure that the specifications on the 1500 watt device clearly show that the voltage range is 220 - 240 volts. It certainly can, but it would depend on the fuse rating and existing load on the circuit.
How many ac amps is a 1500 watts?
Watts are amps x volts, so w/o the volts the question can't be answered. At 100 volts it'd be 15 amps.
How many 100 watt lamps can be used on a 15 amp circuit at 120 volts?
Divide the total circuit wattage (15 amps x 120 volts = 1800 watts) by the individual lamp wattage (100 watts). This gives you 18 lamps that can be used on the circuit. However, it's recommended to leave some capacity for safety, so a practical limit might be around 15 lamps to be safe.
How many watts in 15 amperes?
There are no 'watts' in '15 amperes'. The watt is used to measure power, whereas the ampere is used to measure current. These are two completely different quantities, so you cannot convert one to another.
How many amps equal 1800 watts at 110 volts?
To find the amperage, you can use the formula: Amps = Watts/Volts. Plugging in the values, you get Amps = 1800 Watts / 110 Volts ≈ 16.36 Amps.
How many volts do you need to light up a 15 watts light bulb?
15.
How many watts in 15 KW?
Formula: Power = voltage times amperage. So, if you have 120 volts: the power 120 volts times 1 ampere equals 120 watts. <<>> 15 kilowatts is the same as 15000 watts.
How many watts for a 15 amp fuse?
That depends on the voltage you use. If there are 120 volts, the power equals voltage times amperage. 120 volts times 15 amps = 1800 watts. Cheers ebs
If a circuit contains 1800 watts of loadthe voltage is 120what is the total amperage?
Volts times amps equals watts, so watts divided by volts equals amps, so 15 amps
Can a 15 amp breaker hold 300 watts at 120 volts?
Yes, it can.
How many watts can a 15 amp 120volt ciruit safely power?
A 15 amp circuit at 120 volts can safely power up to 1800 watts (15 amps x 120 volts = 1800 watts), but it is recommended to only draw 80% of the circuit's maximum capacity for safety reasons. So, in practice, it is best to limit the load to around 1440 watts on a 15 amp 120 volt circuit.
What amp breaker do you need for 1500 watts at 120volts?
To calculate the amperage needed for 1500 watts at 120 volts, use the formula: Amps = Watts / Volts. In this case, it would be 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15 amp breaker for this circuit to accommodate the power load safely.
What is 15amp equivilent to in watts?
You need to know the voltage and Power Factor in the equation Watts = Amps x Volts x Power Factor. Now Power Factor is equal to one for a resistance load and decreases for loads like motors. So for example if you are talking about a home portable electric heater that draws 15 Amps at 120 Volts your Watts would be 15 x 120 = 1800 watts or 1.8 kilowatts.
