What offers resistance to the circuit and limits the amount of current that can flow?
The internal components of a device that has been manufactured by a company adds up to the internal resistance of the device. Some devices are higher in resistance, some are lower. The results that you can see is on the device's nameplate and is represented by the wattage that the device draws.
To answer the second part of the question, the answer is Ohm's law. The current of a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. In other words if the voltage remains the same, the higher the resistance the lower the current draw. A short circuit is no resistance, very high current. This is why over current protection is needed in most electrical circuits.

How does a rheostat make a current high?
A rheostat is a variable resistor that can increase or decrease the resistance in a circuit. By increasing the resistance in the circuit, the rheostat limits the flow of current, causing it to become higher in the parts of the circuit where the resistance is lower.
What is the condition that limits the flow of electrons in an electric circuit is called?
The condition that limits the flow of electrons in an electric circuit is called resistance. Resistance is measured in ohms and is caused by factors such as the material of the conductor, its length, and its cross-sectional area.
How a fuse controls the flow of electric current in a circuit?
A fuse does not control the flow in a circuit, it limits the current in a circuit. If the load in a circuit shorts out the fuse link melts and opens the circuit and stops the current flow and prevents the wires feeding the circuit from melting and catching fire. resist
When happen to the voltage when ressistor added to a circuit?
Just as the name of the component implies, electrical current gets resisted and therefore it diminishes unless an equally, larger voltage difference in that section of the circuit is applied. V=IR Current is inversely proportional to Resistance (when one goes UP, the other goes DOWN) Voltage is directly proportional to Resistance
What do you call a substance that offers resistance?
A substance that offers resistance is called a resistor. It is a component in electronic circuits that limits or controls the flow of electric current.
How do resistors affect current flow in an electrical circuit?
Resistors in an electrical circuit reduce the flow of current by impeding the movement of electrons. They create resistance, which limits the amount of current that can pass through the circuit.
How does a resistor work to limit the flow of electric current in a circuit?
A resistor limits the flow of electric current in a circuit by providing resistance to the flow of electrons. This resistance reduces the amount of current that can pass through the circuit, helping to control the flow of electricity and prevent damage to components.
What is the name of a device that can be used to control the amount of current?
A resister limits the amount of current passing through a circuit.
How does a rheostat make a current high?
A rheostat is a variable resistor that can increase or decrease the resistance in a circuit. By increasing the resistance in the circuit, the rheostat limits the flow of current, causing it to become higher in the parts of the circuit where the resistance is lower.
What effect would thinner wire have in a circuit?
The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.
What is the difference between high impedance and low impedance?
The difference between high impedance and low impedance is the amount of resistance in an electrical circuit. High impedance means there is a high level of resistance, which limits the flow of current. Low impedance means there is a low level of resistance, allowing for a greater flow of current.
What is series dropping resistor?
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
What limits the current that flows through a circuit for a particular appllied DC voltage?
The voltage applied and the resistance across it.
How does resistance affect the current in a circuit?
Resistors are used for many things in an electronic circuit, including creating a voltage drop at some point; attenuating noise on a signal before it reaches the output stage; in combination with transistor devices, split a signal into 2 opposite phases; present a minimum load to a device to keep it working at its optimum point; to create an appropriate bias level for transistor device inputs; to control a timing circuit in conjunction with a capacitor; to create a tuned circuit in conjunction with an inductor, and/or a capacitor . . . . and the list goes on . . .
What limits the current that flow to a circuit for a particular applied DC voltage?
The current that flows in a circuit for a given applied DC voltage is primarily limited by the circuit's resistance, as described by Ohm's Law (I = V/R). Higher resistance results in lower current flow for the same voltage, while lower resistance allows more current to flow. Additionally, factors such as the characteristics of circuit components (like diodes or transistors), the temperature of the materials, and the presence of any circuit protection devices can also influence the current.
What does a resistor do in in a circuit?
A resistor is a device that impedes or limits the flow of electrical current in a circuit. It converts the current's electrical energy into heat (thermal) energy. A resistor reduces the amount of energy in a circuit and pumps it out as a heat.
