Kirchhoff's Voltage Law is good for most applications in electrical engineering. One limitation is that the law does not apply when there is a fluctuating magnetic field present.

Why Kirchhoffs current law and Kirchhoffs voltage law cannot apply on distributed circuits?

Actually, they do apply.Kirchoff's Current Law states that the signed sum of the currents entering a node is zero. This applies whether the node has only two connections, such as in a series cicuit, or more than two connections, such as in a parallel circuit. Some people confuse this with the rule that current at every point in a series circuit is the same. That is just a special case of KCL, but the real rule has to do with the node, and not the circuit.Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. This applies for simple series circuits as well as for complex series/parallel circuits. Pick any loop in a circuit and walk around it - you will find that the signed sum of the voltage drops is zero, no matter what.


What is the symbol for voltage in ohm's law?

Voltage = Current x Resistance is often written V = I x R. Ohm's Law is: E = IR E is voltage


What is kvl?

It is Kirchhoff's Voltage Law.


How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?

If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.


What is the application of kirchoffs voltage law?

Kirchoff's Voltage Law: The sum of the voltage drops across all elements in a series circuit add up to zero. If you know the voltage drops across all but one element, and you know the voltage rise across the source, then you can easily calculate the remaining drop.
