In which circuit does charge reverse direction many times per second?

In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.

what term describes the amount of charge that passes a point in a circuit each second Current Resistance Voltage power?
Current
What is 6240000000000000000?
One ampere of curent is equal to the charge of 6,240,000,000,000,000,000 electrons flowing past a given point in a circuit per second.
How much current flows through a circuit if 2 coulombs of charge flows each second?
Current in amperes is coulombs per second, so 2 coulombs per second is 2 amperes.
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!
If a battery sends a current of 10 amps through a circuit for one hour how many coulombs will flow through the circuit?
If a battery sends a current of 10A through a circuit for one hour how many coulombs will flow through the circuit?
Draw two circuit diagrams to show how a change in direction of rotation of series motor is achieved.The first diagram must represent forward rotation and the second the reverse rotation?
DC machine
What does charge actually mean?
Charge is the number of electrons that pass a point in a circuit per second. Hence Q=It
What is the charge flowing per second in a circuit?
The numerical representation of one coulomb of charge moving past a point in a circuit per second is called an ampere.
When 5 coulombs of charge per second pass a point in an electric circuit the electric current in that part of the circuit is?
2 amperes
What is the difference between altenating current and direct current?
The current (or electrons if you will {but thought of as flowing in the opposite direction} in a DC circuit flows only in one direction. In an AC circuit the current periodically flows in the opposite direction (in the US this usually happens 120 times a second, so 60 cycles per second.)
What goes around a circuit?
Charge, in the form of electrons, flow through a circuit. This is called electric current. 1 amp = 1 coulomb of charge per second flowing past a point in the circuit.
What does a coulomb measure?
A coulomb is a unit of electrical charge. It is the charge that passes a point in an electrical circuit in one second when a current of 1 ampere is flowing through the point.
Why does a satellite doesn't charge it's direction quickly?
Any quick change of direction requires a powerful force (according to Newton's Second Law).
A charge of 15 Coulomb flows through any area in a circuit each second the current is?
15 ampere. Since current = charge / time
what term describes the amount of charge that passes a point in a circuit each second Current Resistance Voltage power?
Current
What is 6240000000000000000?
One ampere of curent is equal to the charge of 6,240,000,000,000,000,000 electrons flowing past a given point in a circuit per second.
When there is a difference in voltage the flow of charge is called?
flow of charge is called current. but the direction of flow of current is always taken oppsite to the flow of charge.
