What happens if the direction of current at the terminals of a series motor is reversed?

No changes will occur by wiring a 110 volt motor in reverse polarity, rotation will always be the same. Some single phase motors are designed to be reversed ,but that is a function of the relationship of start windings and capacitors and requires some wiring changes in a motor junction box or an end terminal housing, not by just changing the incoming power.

What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
What happens when collector and base of a transistor are short?
this transistor is common emitter configurated transistor nd if emmiter nd collector both terminals are reversed bias then no current will be flowing through th terminal...
What happens to the meter reading when you invert the direction of the arrow on the current transformer of power meter?
The wattmeter will read downscale (backwards).
What is the meaning of current lags voltage?
'Current lags voltage' means that in the AC cycle the voltage peaks and the current peaks a little time (a fraction of a cycle) later. This happens with electrical loads like motors. When the current lags, there is a small period in each half-cycle when the voltage has reversed and the current has not reversed yet. This causes power to flow back into the supply from the load. So there is a loss of average power fed to the load for a given voltage and current. In this situation the power is the voltage times the current times the power factor, and the power factor is the cosine of the angle by which the current lags the voltage (counting 360 degrees as a full cycle).
What happens to the direction of the magnet field about a straight section of wire when the direction of the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
What happens to the force generated by the circular coil of Relay if current direction is reversed?
As long as the amperage stays the same, the force in the relay stays the same regardless of direction of the current.
What happens to a current carrying wire in a magnetic field if the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
What happens to a current carrying wire in a magnetic field when it is reversed?
the wire would be deflected perpendicular to the magnetic field in the opposite direction.
What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
What happens to magnetic field of a wire when you change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
What happens if you swim into an eddy?
You are either pushed the opposite direction of the current or go nowhere.

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 happens when a microphone polarity is reversed?
it does not work
