What else can I help you with?
Total opposition to current flow in an AC circuit with both resistance and reactance is called?
Impedance.
What effect does decreased resistance have on a circuit?
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
What device is needed for current to flow in an electric circuit?
Too vague of a question. As long as it is a closed circuit it will flow.
If an inductor and a switch are connected in parallel through which the current will flow in an AC circuit?
A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.
The term for the flow of electrons through a circuit is?
electric current
Why current is maximum in series resonance circuit?
Because the only opposition to current flow is the resistance of the circuit. This is because, at resonance, the vector sum of the inductive and capacitive reactances is zero.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
What forces can oppose current flowin an ac circuit?
In an AC circuit, the main opposition to current flow comes from the resistance in the circuit components. Additionally, reactance, which is the opposition to the change in current flow caused by inductance and capacitance, can also play a role in limiting current flow. Finally, impedance, which is the total opposition to current flow in an AC circuit, is a combination of resistance, inductance, and capacitance.
What is the term for opposition to current flow within a circuit?
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
What is the unit to measure the opposition to the flow of electrical current called?
Answer: Inductive reactance is the opposition to the change in current in an electrical circuit and is abbreviated Xl. Answer: The opposition to current flow is called resistance (for DC), or impedance (for AC; often just called resistance); the unit for both is the ohm.
What is the opposition to flow of current in a circuit called?
The opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
Difference between inductance and inductive reactance?
The opposition to AC current flow in a circuit due to induction is called inductive reactance.The process of generating electrical current in a conductor by placing the conductor in a changing magnetic field is induction or just induction.
What factors affect the inductive reactance of a coil in a A C circuit?
Current Flow I believe.
Total opposition to current flow in an AC circuit?
I oppose alternating current. Direct is the only way for me. That is 1 in opposition.
What is describe as the total opposition to current flow in a circuit?
Total resistance.
Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
What is resistance reading?
A measurement of opposition to electric current flow in a component or circuit.
