A circuit carrying current in one direction is called a?
A circuit carrying current in one direction is called a direct current (DC) circuit. In a DC circuit, the flow of electric charge is constant and does not change direction. This is in contrast to an alternating current (AC) circuit, where the flow of electric charge changes direction periodically. DC circuits are commonly used in electronics and power transmission systems.
What is hystersis loss?
As the emf in an AC circuit causes current flow in the core of an inductor the magnetic dipoles will align themselves with the direction of the flow. As the current reverses the dipoles tend to stay aligned and there is a certain amount of flow that is required to realign them in the opposite direction. Thus there is a lag between current reversal and dipole realignment. The energy used for this realignment so to speak is called hysterisis and is a loss to the circuit.
What is reversing key related to physics experiment?
a reversing key is used in the circuit to reverse the direction of current in the circuit.
What is the difference between DC and AC?
The primary difference between DC and AC is the direction of current flow. In a DC circuit, all electron current flow is in one direction. In an AC circuit, current flows in one direction for part of the time, and in another direction for another part of the time. In the AC circuit, we'll see current flowing "back and forth" instead of the unidirectional current flow we find in a DC circuit.DC is "Direct Current", and AC is "Alternating Current". In DC, the current flow is in one direction only. In AC, the current flow is constantly changing direction.An example of DC is the output of a battery. An example of AC is the power present in a home electrical system.The current whose magnitude and direction remains change called as alternating current.The current whose magnitude and direction remain unchanged called as d.c. Current.
How does current flow around a circuit?
current in a circuit will flow in a unidirectional manner and when it passes through a resistor in the circuit it opposes its direction
Why is it required to vary the field current in only one direction while performing the open circuit test on dc generator?
rectification to the negative voltage
What is the direction of current in the circuit?
Circular,,,from the word circuit.

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 direction of current flow in a DC circuit?
In a DC circuit, the direction of current flow is from the positive terminal of the voltage source to the negative terminal.
Why is required to vary the field current in one direction while performing the open circuit test?
Varying the field current in one direction during the open circuit test helps establish a consistent magnetic field in the machine, allowing for accurate measurement of the generated voltage. This method ensures that the relationship between field current and voltage is linear and helps avoid hysteresis effects that could arise from reversing the field current. Additionally, it simplifies the analysis of the machine's performance characteristics, such as the voltage regulation curve.
In what circuit does the current flow in one direction and then in the opposite direction?
on a three way switch.alternating current.
How the direction of electric current differs from the direction of electrons in a circuit?
Circular,,,from the word circuit.
When electrons are moving from negative pole to positive pole in the circuit then current in the circuit will be moving in which direction?
always current flow from the opposite direction of electron
Can the current be negative in an electrical circuit?
Yes, the current in an electrical circuit can be negative if it flows in the opposite direction of conventional current flow.
What should you do to verify the direction of the induced current in a circuit?
To verify the direction of the induced current in a circuit, you can use the right-hand rule. Point your right thumb in the direction of the changing magnetic field and curl your fingers. The direction your fingers curl will indicate the direction of the induced current.
What is required for a circuit to have a current?
a power source
