This term is normally applied to three-phase loads, and describes a situation in which each of the three loads is different in terms of its resistance and reactance. In the case of a wye (star) connected load, this will result in a neutral current flowing -which wouldn't be the case if the loads were 'balanced' (i.e. identical in all respects). You basically have a top heavy circuit that wants to fall over

Difference between a balanced and unbalanced bridge circuit?
A balanced bridge has zero volts across the two test nodes, while an unbalanced bridge has non zero volts.
What happens if neutral of three phase four wire system is break?
For a balanced three-phase load, the neutral current is zero, so the loss of the neutral would have no effect.However, for an unbalanced load, the 'difference' between the line currents results in a neutral current.So, for an unbalanced load, if no neutral current can flow, then the load's neutral point will no longer remain symmetrical, and the line voltages will become unbalanced. If the unbalance is severe, then individual loads may be subject to over-voltages or under-voltages.
Why link is provided as neutral in an ac circuit?
link is provided in neutral path of ac supply because it should provide a path for unbalanced currents , if we use fuse ,fuse may blow of and damage the entire system and also unbalanced currents may be more than the fuse rating
What is the difference between unbalanced transportation and unbalanced assignment problem?
model sum
How do you get line to neutral voltage form line to line voltage especially when there is unbalance in line to line voltage?
It is highly unusual for the supply system's line voltages to be unbalanced as the source is considered to be an infinite bus. On the other hand, it is not in the least unusual for the line currents to be unbalanced, as they are determined by the load. If a unbalanced star (wye) connected load has no neutral, then the phase voltages will become unbalanced.

Why are forces unbalanced?
forces can be unbalanced because they are at differant hights there fore they are not at equal hights so they are unbalanced.
Pictures of balanced and unbalanced forces?
this is unbalanced forces.
What is the result in unbalanced forces?
The result of unbalanced forces is a net force that can accelerate a body.
Is an unbalanced desk an example of an unbalanced force?
No. There is no such thing as a single force that is balanced or unbalanced, and a desk is not a force anyway.
When do you say that the force is unbalanced?
When an object accelerates, the force is unbalanced.
How do you use the word unbalanced in a sentence?
the man was unbalanced on the ball
If you push a box until it moves is it unbalanced or balanced?
Unbalanced
What kind of force create movement balanced or unbalanced?
unbalanced
Give one example of an unbalanced force?
unbalanced forces cause acceleration, an object in freefall has gravity as an unbalanced force.
How do rickets lead to an unbalanced diet?
