i have a similar problem but mine doesn't need to be controlled with a dial. i think a carbon pile may be your answer. an old carbon pile battery tester through the circuit. either that or several resistors, select amount of resistors your circuit passes through with your dial switch, like a blower motor in your car would use. my problem however is finding a way to limit amps to 75 between two sets of batterys where amps have the potential of fluctuating from 0 to2600. a cannot just put a resistor in the circuit because they resist a set amount of ohms rather than only let a set amount of amps pass through. like a breaker or fuse. but i don't want a breaker or fuse because the circuit will be broken with them. I'm working on a 12v dc circuit. I'm not sure how a carbon pile will react on ac but it something to think about.
What else can I help you with?
What happens to amperage in series and parallel circuits?
In series, Amperage remains constant. In parallel, Amperages are added.
Is 110 volts 10 amps?
Voltage and Amperage are not directly dependent upon each other. Electricity is like water in the way that it "flows". Voltage is analagous to water pressure (like PSI), whereas amperage is analagous to the amount of water actually flowing (like gallons-per-minute). As voltage increases, amperage typically decreases and vice versa. But the actual amperage of a 110 V circuit depends on the device connected to it and how much current it draws. For instance, a 12 amp vaccuum cleaner is gonna draw 12 amps out of a 110 V circuit, whereas a 60 watt light bulb connected to the same circuit is gonna draw about half an amp (amperage=wattage/voltage, or amperage=60/110).
How much amperage a hair dryer draw?
A typical hair dryer draws around 10-15 amps when operating at its highest setting. It is important to check the specific amperage rating of the hair dryer you are using to ensure it is compatible with the electrical circuit you are using.
How is the strength of electric current measured with?
The strength of an electric current is measured in amperes (A) using an ammeter. An ammeter is a device that is connected in series in a circuit to measure the flow of current. The higher the current flowing through a circuit, the higher the amperage reading on the ammeter.
When does overloading in electricity occur?
Overloading in electricity occurs when the electrical circuit is carrying more current than it is designed to handle, resulting in overheating and potential damage to the circuit components. This can happen when too many devices are plugged into a single outlet or when a high-powered device is used on a circuit with a low amperage rating.
How do fuses protect wires from overheating?
The fuses restrict the amperage (electrical current/flow) of the circuit. The fuse is size according to wire size and load requirements. NEVER put in an over-sized fuse as it will allow to much amperage for the circuit which will cause overheating of the circuit and possible fire.
What is the cause and how would you correct a blown fuse?
The purpose of a fuse is to restrict amperage traveling through an electrical circuit to a specified value. It does this by inserting itself into the circuit and running the current through a metal strip inside the fuse. When the circuit is carrying to much amperage the metal strip will heat and then melt away, breaking the circuit and protecting anything that would be damaged due to the overload. In order to correct it, you must locate the fuse, remove it, and replace it with a new fuse of the same amperage rating.
What is a amperage relay?
An amperage relay is an electrical device used to activate or deactivate a circuit based on the current flowing through it. It is designed to protect the circuit from overload or short-circuit conditions by opening or closing the circuit when the preset amperage level is exceeded.
What is the range of amperage for the electrical circuit in question?
The range of amperage for the electrical circuit in question is between 15 to 20 amps.
What is the maximum amperage rating for a circuit breaker that can safely protect a 20 amp circuit?
The maximum amperage rating for a circuit breaker that can safely protect a 20 amp circuit is 20 amps.
What is the maximum amperage capacity of a 150 amp circuit breaker?
The maximum amperage capacity of a 150 amp circuit breaker is 150 amps.
What is the maximum amperage capacity of the circuit breaker 30 amp?
The maximum amperage capacity of a 30 amp circuit breaker is 30 amps.
What is the maximum amperage capacity of a 60 amp circuit breaker?
The maximum amperage capacity of a 60 amp circuit breaker is 60 amps.
What is the maximum amperage capacity of a 90 amp circuit breaker?
The maximum amperage capacity of a 90 amp circuit breaker is 90 amps.
Open circuit prevents the movement of what?
amperage
How do you pick the right fusible link?
Fuses are based upon the size of the wire of the circuit that it is to protect. The wire is sized by the amperage of the connected amperage load of the circuit.
What is the maximum amperage capacity of the circuit protected by 30 amp breakers?
The maximum amperage capacity of the circuit protected by 30 amp breakers is 30 amps.
