What else can I help you with?
What is a material that slows down or resists the flow of current and is used in electrical systems?
Resistor
Does resistance flow through a circuit?
No. Resistance does not flow. Resistance is the characteristic of a material that resists the movement of electrons and thus the flow of electrical current.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
When current remains constant and resistance increases the voltage in the circuit will?
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
How can you stop electric current?
An insulative material is one that will stop the conduction of heat. This would be considered a thermal brake and could be a piece of plastic or wood.
The opposition to the movement of charges flowing through a material is called what?
The opposition to the movement of charges flowing through a material is called resistance. It is a property that determines how strongly a material resists the flow of electric current.
Describe how the resistance of a material is determined?
The resistance of a material is determined by its resistivity, which is a fundamental property of the material. Resistivity is a measure of how strongly a material resists the flow of electric current. It depends on the material's composition and its physical dimensions. The resistance of a material can be calculated using the formula: resistance = resistivity x (length / cross-sectional area).
What is a material that slows down or resists the flow of current and is used in electrical systems?
Resistor
What is the difference between resistance and the resistivity?
Resistance is the value of a given wire in ohm but resistivity is value of the material with which that wire is made in ohm meter. R = rho * L / A Here rho is resistivity and R is resistance. L is the length of the wire and A is area of cross section
What do you call the material that resist the flow of electric current?
The material that resists the flow of electric current is called an insulator. Insulators have high resistance to the flow of electricity and are used to prevent electricity from flowing where it is not desired.
What are resistors and what are they important?
Resistors are a material that resists the flow of electrons. The resistors are materials that resist electric current energy to be changed into other forms.
What are Ohms the measurement of?
Ohms are the unit of measurement for electrical resistance. It indicates how much a material resists the flow of electric current.
What are resistors and why are importanted?
Resistors are a material that resists the flow of electrons. The resistors are materials that resist electric current energy to be changed into other forms.
Does resistance flow through a circuit?
No. Resistance does not flow. Resistance is the characteristic of a material that resists the movement of electrons and thus the flow of electrical current.
Is it true that a material with high resistivity is a good conductor?
No, a material with high resistivity is a poor conductor. Resistivity is a property that quantifies how much a material resists the flow of electric current. Materials with high resistivity impede the flow of current, making them poor conductors.
How measure of how a mineral resists scratching?
hardness
Is a measure of how well a mineral resists scratching.?
Hardness.
