By Decreasing the excitation voltage the terminal voltage will decrease and similarly by increasing the excitation voltages the terminal voltage will also increases.

.The magnitude of the voltage and current of both the armature and shunt field coil. To decrease the speed when the load is increasing then increase the shunt field current while decreasing the armature voltage or current. To increase the speed while the load is increasing then increase the armature current while decreasing the shunt field current. The decreasing and increasing of these currents and voltages can be done by connecting a variable resistor in series or parallel with each of the armature and/or shunt field coil.
Some generators are self excited; this means their terminal voltage is fed back to the excitation system to supply power to the rotor of the generator (which makes it into an electromagnet); the more power that is fed back, the stronger the electromagnet becomes, which makes it harder to turn the generator, which causes the generator to push out more power (simplified, really quick version). If there is a fault electrically near the terminal of a self excited generator, the terminal voltage will sage to near zero; this means the voltage supplied to the excitation system will drop by the same percentage (say the terminal voltage is 30% of what it should be, then the maximum supplied voltage to the excitation system drops to 30% of what it normally is, since P = V*I). Since the input power is less, the output of the generator will decrease (current will decrease). The terminal voltage is determined by the impedance between the generator and the fault such that V = I*Z; As I decreases, V will also continue to fall, causing the terminal voltage to sag even more. A non-self excited generator gets its' excitation power from the grid, specifically from a location that is electrically separated from its' terminal voltage. If the terminal voltage sagged to 30% (same fault location as above example), the excitation system voltage may be impacted slightly (say 2%) so the excitation system power is near maximum (98% for this example). Since the excitation system is much farther removed from the terminal voltage, it is not dependent upon it, thus the terminal voltage will not continue to sag as with a self excited system.
To reduce kWh by capacitor is when a motor is put in. The terminal voltage is reducing and current is increasing it is connected parallel with the motor.

excitation voltage is sinusoidal because it is taken from the terminal of alternator but excitation current is non-sinusoidal because it always dc.
The generator terminal voltage will increase.

I'm reluctant to answer because the wording of the question suggests the person asking is looking for answers that meet undefined constraints. One way to increase the terminal velocity of a falling object is to drop it in a vacuum. Another is to drop it in a atmosphere of hydrogen. . 1. increase the mass, without increasing the drag coefficient. 2. Decrease the drag coefficient, without decreasing the mass.
The positive + terminal is slightly larger.
Of course. The magnitude (size) of acceleration is the rate at which speed is changing. As long as the magnitude of acceleration is more than zero, speed is increasing. If the magnitude of acceleration is decreasing, then speed is growing more slowly, but it's still increasing. That's exactly what's happening to an object falling through air. As it falls faster and faster, the force of air resistance increases. The object's acceleration shrinks, and it's speed increases more slowly. When the force of air resistance is equal to the object's weight, the net force on it is zero, its acceleration is zero, and its speed stops increasing. It's then at 'terminal velocity'.
Terminal provides infrastructure for the port to handle containers.
