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
What is the function of galvanometer in the bridge circuit?
In a bridge circuit, a galvanometer is used as a sensitive measuring instrument to detect small differences in potential between two points. It indicates whether the bridge is balanced or unbalanced by showing a current flow or deflection in its needle. When the bridge is balanced, the galvanometer reads zero, allowing for precise measurements of resistance or impedance in the circuit. This function is crucial in applications such as Wheatstone bridges for determining unknown resistances.
What is an unbalanced circuit?
An unbalanced circuit refers to an electrical circuit where the components or loads are not symmetrically distributed, leading to unequal voltage or current across different branches. This can result in imbalances in performance, increased losses, and potential overheating of components. Unbalanced circuits are common in single-phase systems and can affect the overall efficiency and stability of electrical systems. Proper design and analysis are crucial to mitigate the negative effects of unbalanced conditions.

Is an unbalanced desk an example of an unbalanced force?
No, an unbalanced desk is not an example of an unbalanced force. An unbalanced force refers to a force that causes motion or a change in motion, while an unbalanced desk is simply an object that is not level.
When do you say that the force is unbalanced?
When an object accelerates, the force is unbalanced.

When an unbalanced force acts on an object the object will?
When the entire group of forces acting on an object is unbalanced,the object will accelerate.There's no such thing as "an unbalanced force".
What determines wire size for 3-phase electrical circuits?
there are various parameters to be cosidered in the design of the wire size such as voltage, current ratings, length of circuit, whether circuit is balanced or unbalanced, conductivity of the material used for the wire etc. There are different formulae for different conditions. if you want, i can give you.
