What would happen to an electric motor if the amount of current in the motor was reduced?

Depends on what sort of motor it was. If it was the sort you find in an ordinary electric drill, then it would slow down. But rememer, the only way you can reasonably reduce the current in to motor is to reduce the voltage in the supply. A motor takes what current it can, dependent on Ohm's Law. To reduce the current, reduce the voltage.
But in a three-phase motor, the speed being dependent on the rotation of the phases, it would more or less stay the same. But this assumes it's not under load. A load would cause it to slow down.

Do all currents provide the same amount of energy?
Of course not! There is no direct relationship between electric current and electric energy. They aren't even measured in the same units. Also in most cases small electric currents provide less electric energy that very large electric currents. If all electric currents provided the same electric energy then the electric current from a flashlight battery that lights the bulb when you turn the switch on could provide the same electric energy as the electric current in a lightning bolt when it strikes... therefore every time you turned on a flashlight the electric energy would destroy the flashlight and electrocute you! As this doesn't happen, the only answer that your question can have is no!
What must happen to the electric current in power lines before it can safely enter your home?
step-down transformer
What happen to current when paralle resistor added?
For the individual resistor, the current is constant, regardless of any other resister that's attached to it in parallel. The current that results from all the resistors combined decreases as the resistance of one or more of the resistors increases.
What will happen to the current if you add more bulbs to the cirrect series?
current will decrease
Is it possible to transmit power with leading power factor?
The power factor depends on the properties of the load, and if any power factor correction is done it has to happen at the load, so that the current in the transmission lines is reduced. Correcting the power factor at the sending end fails to address the problem.
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?

What would happen if the amount of greenhouse gases were reduced?
If the amount of greenhouse gases were reduced, then the temperature of the earth would cool.
What would happen if you reduced the resistance in a circut?
current will increase
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What will happen to an electric wire if a large current passes through it?
It will get hot.
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What relation between electric current and drift velocity?
The relation between electric current and drift velocity is that they both happen to involve electrons moving opposite of the electric field. The electric field must also have a conductor.
What happen if you reduced the number of devices on each parallel circuit?
The overall current will decrease by subtracting the current used by each device.
What will happen if an electric current comes in contact with another electrical current?
They Attract: F = iL x B
What will happen to the emitter current if the emitter base is reversed biased?
as we know that in reverse bias condition no current is produced and if it produced by the minority charge carrier then also the current produced is in very less amount so u can say that emitter current will reduced to large extend as compare to emitter current in forward bias condition
What would happen to the amount of photosynthesis if the number of chloroplast s was reduced by half?
Photosynthesis happening because of chloroplasts. it will reduce if chloroplasts are reduced.
When a current flows through an electric bell what will happen to the armature?
When current passes through an electric bell, the armature gets magnetised and attracts the gong hence ringing the bell.
