What kind of current flows in the armature conductor of a dc generator?
pogi current flow in the armature conductor
How the direction of EMF depends on the direction of current?
Current flow is from positive to negative. Use the left hand rule for finding the north and south poles. Grab the coil in your left hand, with your fingers wrapped around the coil in the direction of the current flow. Your thumb will then point toward the north pole of the coil. Reverse the positive - negative connections to the coil and the north - south poles will change ends. The left hand rule will still be in effect as the current will now be flowing in the reverse direction as it was in the first connection.
The expression alternating current refers to which form of energy?
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
How does a diode respond when a current source is connected?
The current will flow in one direction only. That direction is indicated by, usually, a ring around one end of the diode. The current will flow from the unmarked end to the marked end.
The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
Why direction of rotation is not reversed when both field and armature terminals are reversed?
The direction of the force that drives the machine is determined by the relative directions of the field and the armature current. By reversing the direction of both field and the armature current, the direction of the resulting force stays the same; you have to reverse the direction of one or the other; not both! Prove it for yourself, by applying Fleming's Left-Hand Rule (for conventional current flow); reverse the direction of both your first finger (field) and your second finger (armature current), and you thumb (direction of motion) will end up pointing in the same direction!

The polarity of an electromagnet is determined by what?
the direction of the flow of current
What kind of current flows in the armature conductor of a dc generator?
pogi current flow in the armature conductor
When the flow of a current is aways in one direction?
When the flow of current is aways in one direction it is known as direct current.
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.

Grab the coil in your left hand, with your fingers wrapped around the coil in the direction of the current flow. Your thumb will then point toward the north pole of the coil. Reverse the positive - negative connections to the coil and the north - south poles will change ends. The left hand rule will still be in effect as the current will now be flowing in the reverse direction as it was in the first connection.
What is a Generator consisting of a coil that rotates between the electromagnet causing a current to flow in the armature?
dynamo
Which type of current involves charge flow in single direction?
A direct current involves change of flow in a single direction.
What current that does not reverse its direction of flow?
direct current
How does relay works?
Current is supplied to the electromagnet and magnitised and attract the soft iron armature. Then it closes the contact allowing the current to flow.
