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.

Kirchoff's Voltage and Current Laws apply to all ac circuits?
Kirchoff's Voltage and Current Laws apply to all AC circuits as well as DC circuits. Other laws, such as Ohm's law and Norton and Thevanin equivalents apply equally as well. The complicating factor is that, at AC, current and voltage are not usually in phase with each other, unless it is a simple resistive circuit. That makes the math harder, but it does not make it invalid or impossible.
Why do you replace voltage sources with short circuits and current sources with open circuits in thevenin's theorem?
The equivalent of an inactive Thevenin voltage source is a source with zero voltage between its terminals regardless of the current through it, best represented by a zero resistance, i.e. a short-circuit. The equivalent of an inactive Norton current source is a source through which no current can flow regardless of the voltage across it, best represented by an infinite resistance, i.e. an open circuit.
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
When would you use current transformer?
A 'current transformer' (CT) is classified as an instrument transformer, which means it is used to provide a small secondary current that is in proportion to its large primary current, for purposes of metering or protection. At the same time, it electrically-isolates the secondary (metering) circuits from the primary circuits (which are often high-voltage circuits) for the purpose of safety.
Which starting system component uses a small amount of current to control a large amount of current?
I think its a starter solenoid or a relay. I know relays take high voltage current to power low voltage circuits. Hope that helps..
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
What is the same in a parallel circuit?
Always voltage constant in parallel circuit if you look your house wiring all are in parallel therefore 220 volt present in every house but current is different
What are the mathamatical relationships in Ohm's Law in AC circuits?
Ohm's Law Voltage = Current x Resistance Current = Voltage divided by Resistance Resistance = Voltage divided by Current
How is power and voltage related?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
In RC circuits the voltage leads the current?
Inductive. Used to remember this by "Eli" the "ice" man. "(e) Voltage (l) (Inductive circuit) (i) current", the ,"(i) Current (c) (capacitive circuit) (e) voltage, man.
What is the cause of voltage drop in electrical circuits?
Voltage drop in electrical circuits is caused by the resistance in the circuit components, such as wires, connections, and devices, which leads to a decrease in voltage as current flows through them.
Do relays use high voltage to control low currant circuits?
Low voltage to operate relay controlling high CURRENT circuits (currant is a dried fruit).
Why you are using rectifiers in electronic circuits?
To convert voltage to DC .*(Direct Current)
Do neutral wires have voltage in electrical circuits?
No, neutral wires do not have voltage in electrical circuits. They are designed to carry current back to the power source and are typically at or near ground potential.
Are voltamps equal to watts?
Yes, in direct current (DC) circuits where the voltage and current are in phase, voltamps (VA) are equal to watts (W). However, in alternating current (AC) circuits where the voltage and current may not be in phase, the relationship between voltamps and watts can vary depending on the power factor of the load.
What is the correct relationship among power current voltage?
Power is the product of current and voltage (P=IV). Voltage is the potential difference that drives current through a circuit, while current is the flow of electric charge. The relationship among power, current, and voltage is crucial in understanding and analyzing electrical circuits.
What are the 2 advantages of 24 Volt current?
Low voltage circuits are any circuits under 30 volts, usually 24 volts. 24 volt circuits are usually control circuits. The amount of current in these systems is usually small, under 5 amps. Since the voltage and amperage is very low, wiring can be much smaller and therefore much cheaper to install than "line" voltage wiring. Low voltage is also much safer.
