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.
What else can I help you with?
If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?
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
How many amps in 6 kw?
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.
What is an electric flow?
An electric flow, is Current. Measured in Amps(Amperes)
What unit of measure is used to measure current?
Ampere is the unit used to measure the current.
How many amps do 8 6 volt dc batteries put out?
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.
What is the amperage of a 20 HP 240v single phase motor?
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.
What is the difference between 5 amps and 10 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.
If an electric unit pulls 33 amps with a supplied voltage of 240 volts what would the kilowatt output be?
Watts = Amps x Volts. 33 x 240/1000 = 7.9 Kw
How many kilowatts does 7 amps pull?
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.
What is a Kiloampere?
It is a HUGE amount of current 1000 amps
Why do sparks jump when you pull the plug of a vacuum cleaner but not when you pull the plug of a lamp?
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
Is as strong 12 amp drill or 19.2 amp drill?
The more amps any tool pulls, the stronger it's motor is.
How many amps does an iron pull?
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.
Why do ammeters need to be part of the circuit?
To measure the amount of amps (A).
What is the error voltage in op amps?
The amount by which it deviates from ideal.
A 500 watt pool light pulls how many amps?
To answer this question the voltage of the bulb is needed.
What is a starter relay?
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.
