Ohm's Law
E = I x R
R = E/I = 60/25
W = Amps times Volts. A = W/V, A = 300/120 = 2.5 amps
60/25 Ohms.
Using the equation Volts X Amps = Watts, you can take 3000 watts / Volts to get your answer: 3000W/240V = 12.5A or 3000W/120V = 25A So, at 240 volts you will use 12.5 amps for 3000 watts of power. Or at 120 volts you will use 25 watts.
To calculate the amperage for a given wattage, you would also need the voltage of the circuit. However, if we assume standard 120V household voltage, then 3000 watts would be equivalent to 25 amps (3000 watts / 120 volts = 25 amps).
75 Amps theoretically Need to know if the generator is 3 phase or single phase.
You have to rewire the circuit completely with 10 AWG wire and replace all outlets and switches with devices rated at 25 Amps. Note 25 Amp breaker is an unusual size. 10 AWG will go up to 30 amps, and that would be the way to go.
I=V/R In words, Amps equals power divided by voltage. So you need to know voltage. Assuming 120 volts, Amps=5600/120=46.7
Amps = Watts / (Volts x Power Factor). Now a hair dryer has a motor and a resistive heater so if we assume a PF = .8 the answer is: 1500 / 20 = 75 amps. Since it is unlikely that you have a 75 amp hair dryer you must mean 125 volts. The answer for that would be 1500 / 100 = 15 amps which is still high, but believable. If we assume a Power Factor of 1 and ignore the motor contribution to Power Factor we have 1500 / 125 = 12 amps.
The 5 amp fuse has many wattages that it can protect. It depends on the voltage of the circuit that the fuse is protecting. Use the following formula, Watts = Volts x Amps. For example 120 volts x 5 amps = 600 watts, 240 volts x 5 amps = 1200 watts, 480 volts x 5 amps = 2400 watts and 600 volts x 5 amps = 3000 watts.
As asked, the question cannot be answered. At 1 volt, 300 Watts = 300 Amps. At 10 volts, 300 Watts = 30 Amps. At 100 volts, 300 Watts = 3 Amps. At 120 volts, 300 Watts = 2.5 Amps. At 240 volts, 300 Watts = 1.25 Amps. To calculate the relationship between Amps, Volts and Watts, use the formula: Watts = Amps * volts
Volts. 12.6 volts = Full Charge 12.4 volts = 75% Charge 12.2 volts = 50% Charge 12.2 volts = 25% Charge
The maximum current rating for the circuit breaker should be at least 30 amps to accommodate the continuous current of 25 amps required by the load.
