A balanced bridge has zero volts across the two test nodes, while an unbalanced bridge has non zero volts.
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.
A voltmeter measures the potential difference between two points,whether or not the two points are in the same circuit.
series circuit can only move on one patha parallel circuit has two more paths for the electric carve to follow
The energy dissipated.
Voltage drop
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
if it is balanced then neutral current is zero (!,e iR=iY=iB).AnswerFor both a balanced and an unbalanced load, the neutral current will be the phasor sum of the line currents.

what is the difference between miniature circuit breaker and fuse
magnetic circit has a magnet and electri circuit has electricity
Voltage and potential difference are essentially the same thing in an electrical circuit. Voltage is the measure of potential difference between two points in a circuit. In other words, voltage is the force that pushes electric charges through a circuit, and potential difference is the measure of this force.
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
because of the reactances in the circuit
The ground wire should carry no current at all, it is there in case of a short circuit to carry the (short circuit) current back to the breaker panel to trip the breaker. The neutral will carry the unbalanced load current between the 240 volt legs. e.g. L1 and N (neutral) 120 volts the load draws 8 amps. L2 and N (same neutral) 120 volts the load draws 12 amps. The difference between the two amperages is what the neutral will carry 12 - 8 = 4 amps.
A voltmeter measures the potential difference between two points,whether or not the two points are in the same circuit.
Potential difference and voltage are essentially the same thing in an electrical circuit. Voltage is the measure of potential difference between two points in a circuit, indicating the amount of energy that can be transferred between those points. In other words, potential difference is the technical term for voltage in the context of electrical circuits.
