Does the voltage between two points in a circuit decrease or increase when the electric field in the circuit increase?
When the electric field in a circuit increases, the voltage between two points typically increases as well. This is because voltage is directly related to the electric field and the distance between the points, following the relationship ( V = E \cdot d ), where ( V ) is voltage, ( E ) is the electric field strength, and ( d ) is the distance. Thus, an increase in the electric field generally results in a higher voltage across the same distance.
What is the purpose of a capacitor in a circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)
How do you know when you have a circuit?
tuned circuit
What is the difference between field current and voltage?
Field Current in a DC Motor is the flow of electrons through the field circuit by a field controller. The flux of the motor, that with the armature current generates torque, is directly proportional to the field current. Field Voltage is the electrical potential energy applied on the field circuit by a field controller. Legacy Field Controllers controlled the field voltage. Using I=V/Z (Z=R+iX) the field current is then indirectly controlled. Due to the heat generated by E=i2 R t in the motor, the resistance R would decrease, increasing the field current and therefore changing the base speed of the motor and disturbing the control. Newer field controllers control the field current eliminating this problem
Explain how you know that it is an electric field not electrons that moves rapidly through a circuit?
Electrons in an active circuit either drift slowly, or just jiggle back and forth in one place.
Is the magnetic field that is near an electrical circuit parallel or perpendicular to the circuit?
Perpendicular to the circuit.
Is a circuit a path made for magnetic field?
A circuit is a path for charge particles -- it conducts current. An inductor, a circuit component, generates a magnetic field, when an AC is on. ======================
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
What is the relationship between the electric field and current in a circuit?
The electric field in a circuit is directly related to the current flowing through it. The electric field is what drives the flow of electric charge, which is the current. In other words, the presence of an electric field is necessary for current to flow in a circuit.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
What is the relationship between the electric field formula and voltage in an electric circuit?
The electric field formula and voltage in an electric circuit are related because voltage is a measure of the electric potential difference between two points in a circuit, and the electric field is the force that causes charges to move between those points. In simple terms, the electric field creates the voltage that drives the flow of electric current in a circuit.
What is the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
Is IT a circuit branch?
IT is short for information technology and is a field of education.
What force causes electrons to move in an electrical circuit?
The force that causes electrons to move in an electrical circuit is an electric field. When a voltage difference is applied across a conductor, the electric field exerts a force on the electrons, causing them to flow through the circuit.
Can a magnetic field affect the performance of electrical circuits?
You better believe it can, but only if it's changing, otherwise the magnetic field can just pull or push the electrons in the circuit towards or away from it, but it can't slow them down. If the magnetic field is changing, a phenomenon called inductance happens. Inductance is an applied current to a circuit by a changing magnetic field. As you might imagine, an additional applied current to a circuit can definitely change the circuit's behavior and alter its performance.
What is the role of the electric field in the wires of an AC circuit?
The electric field in the wires of an AC circuit helps to push and pull the electric charges back and forth, allowing the flow of alternating current.
