In a dc circuit polarity refers to the direction of which flow?

In the US, it is common practice in a DC circuit to refer to the polarity for which "positive (+) charge" is flowing. Positive charge (current) will flow out of a voltage supply's positive (+) terminal which means positive charge will flow into the (+) terminal of a circuit load (resistor, etc).
This is an arbitrary convention and may be reversed in older or foreign textbooks. In such cases all positive (+) references in the previous description would be replaced by negative, (-) notations.

What direction does current flown an ac circuit?
We have suppose the current flow in opposite to the direction of flow of electron.AnswerA.C. current reverses direction every half-cycle.
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
What is the difference between an AC and DC generators?
AC generator, the brushes run on slip rings which maintain a constant connection between the rotating coil and the external circuit. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit varies like a sine wave and the current alternates direction. DC generator, the brushes run on a split-ring commutator which reverses the connection between the coil and the external circuit for every half-turn of the coil. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit fluctuates between zero and a maximum while the current flows in one constant direction
What is equivalent positive flow in a circuit?
Positive electrical flow is electrons flowing in one direction in a wire, if they change the direction of flow that would be a negative flow. If they change direction quickly, say 60 times a second, that would be alternating current, which is what we have in the united states as household electricity.
What refers to electric current when electrons always flow in the same direction in the wire?
When electrons always flow in the same direction in the wire it is known a DC (direct current).
What will happen if you change polarity in parallel circuit?
The current in each branch of the circuit will turn and flow in the other direction.
What does negative polarity mean with electricity?
Polarity is the direction of flow of electrons throughout a circuit. There are two types of polarity: positive and negative. Postive polarity is of older circuits which means electrons flow from positive to negative. Negative polarity is of more modern circuits and that is the flow of electrons from negative to positive such as on car batteries
What is the polarity of a circuit?
The polarity of a circuit is dependent upon the type of circuit. Direct current circuits have one negative pole and one positive pole and they flow in one direction. Alternating current circuits the electron flow reverses because the tow poles alternate between negative and positive.
Define alternating current definition?
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..
The polarity of an electromagnet is determined by what?
the direction of the flow of current
The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
Does a diode have polarity?
Yes, a diode inherently has polarity, as current is only allowed to flow one direction.
What is the purpose of the diode in the GM AC clutch circuit?
The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit. The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit.

What is prince phillip's full name?
The polarity of a circuit is dependent upon the type of circuit. Direct current circuits have one negative pole and one positive pole and they flow in one direction. Alternating current circuits the electron flow reverses because the tow poles alternate between negative and positive.
The battery determines the direction of flow of charge in a circuit?
Yes
In what circuit does the current flow in one direction and then in the opposite direction?
on a three way switch.alternating current.
