You don't really control amps directly. The two easy variables are voltage and resistance. So if you DC source produces a constant voltage, you're going to have to vary the amount of resistance in your circuit to control the amps. The relationship is as follows.
V = I * R
So if you want to more amps for a given voltage, lower the resistance. The extreme would be to short circuit the volt source (simply connect a wire between the voltage terminals), this allow a lot of current to flow throw your circuit.
Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous
UK Mains is 230V therefore 6 KW is 6000/230 = 26 Amps. 3 phase is slightly different....... 6000/400V = 15 Amps/root 3 = 8.67 Amps per phase.
An electric flow, is Current. Measured in Amps(Amperes)
Ampere is the unit used to measure the current.
The amperage drawn from batteries is governed by the connected load. The voltage of the batteries can be one of two voltages. in parallel the 8 batteries will give you a voltage of 6 volts. In series the 8 batteries will give you a voltage of 48 volts. The amp/hour capacity of the batteries will give you the amount of current the device can draw over a specific length of time. Equation to fine amperage is I = W/E, Amps = Watts/Volts. Watts = Amps x Volts.
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
The main difference between 5 amps and 10 amps is the amount of current flowing through a circuit. 10 amps is double the amount of current compared to 5 amps, which means a 10 amp circuit can handle twice as much power without overloading.
Watts = Amps x Volts. 33 x 240/1000 = 7.9 Kw
Seven amps pulls zero kilowatts . W = A x V. You need to state a voltage to multiply the amperage by to get watts. Then divide by 1000 to get kilowatts.
It is a HUGE amount of current 1000 amps
This is due to a higher amperage draw from the vacuum. Where a lamp most likely pulls less than 1/2 amps. The vacuum pulls more as it runs. Therefore the load, or amps, make it harder to break the circuit which causes the sparks
The more amps any tool pulls, the stronger it's motor is.
A typical iron pulls around 9-12 amps when in use. It's important to check the specific amp requirement of your iron to ensure it matches the capacity of your electrical circuit.
To measure the amount of amps (A).
The amount by which it deviates from ideal.
To answer this question the voltage of the bulb is needed.
A relay is a device which uses a small amount of power to control a larger amount of power. In the case of a starter relay, you want to control the large amount of power, sometimes up to 500 amps, flowing through that large cable from the battery to the starter motor. It would not be practical to run that large cable up to the ignition switch and then back to the battery. Instead, a very liitle amount of power (less than 1/10 amp)passes through the ignition switch to the relay, where it operates an electrical magnet that pulls contacts (a switch) together. The large power cables are connected to the switch in the relay, and once the contacts are pulled together the large amount of power is connected to the starter motor to operate it.
