The opposition of current is called?
"Opposition to current" can refer to resistance, reactance, or impedance.
What is coulmb?
(coulomb) A quantity of electric charge. Passage of 1 coulomb per second along a wire is called 1 amp (ampere) of electric current.
What is the physical significance of the impedance?
Impedance may refer to: the ratio of the voltage phasor to the electric current phasor, as in Electrical impedance, a measure of opposition to time-varying electric current in an electric circuit. Characteristic impedance, a measure of opposition to electric current propagation in a transmission line. Impedance matching and Impedance mismatch. Vacuum impedance, a universal constant. Electromagnetic impedance, a constant related to electromagnetic wave propagation in a medium. Mechanical impedance, a measure of opposition to motion of a structure subjected to a force. Acoustic impedance, a constant related to the propagation of sound waves in an acoustic medium. Linear response function, a general way to represent the input-output characteristics of a system. Scroll down to related links and look at an example: "Interconnection of two audio units".
When electrons are not allowed to pass through a material this opposition to current is known as?
The opposition to current in a circuit is known as Electrical Resistance (R) and is measured in Ohms (Ω)
What does electric current produce?
A electric current produces a magnetic field
What is resistance reading?
A measurement of opposition to electric current flow in a component or circuit.
Impedience of electric circuit?
The impedance of an electric circuit is the measure of the opposition presented by a circuit when the current and voltage is applied.
Impedance of electric circuit?
The impedance of electric circuit refers to the measure of the opposition that a circuit presents to a current when a voltage is applied.
What insulators stop electrical current?
Not really, insulators simply cannot support the passage of an electric current.
What material allows electric current to pass through?
Electric current flows in conducting materials such as metals. The best conductor of electric current is silver, followed closely by copper and then aluminium.
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
The instrument used to increase or decrease the passage of electric current through a circuit is called?
try RHEOSTAT
What does tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
What is the opposition to the flow?
resistance is the opposition to the flow of electric charge
