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 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.
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.
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
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.
I think its a starter solenoid or a relay. I know relays take high voltage current to power low voltage circuits. Hope that helps..
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)
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
Ohm's Law Voltage = Current x Resistance Current = Voltage divided by Resistance Resistance = Voltage divided by 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.
That depends on the circuit - but note that in almost all real circuits the current is the dependent variable - you control the voltage and the current sets itself.
Low voltage to operate relay controlling high CURRENT circuits (currant is a dried fruit).
To convert voltage to DC .*(Direct 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.
the common emitter configuration is most widely used in amplifer circuits because of its high voltage,current & power gain.the common emitter configuration is most widely used in amplifer circuits because of its high voltage,current & power gain.
If the current rises and falls with the voltage, then the two are said to be 'in phase'; this occurs in a purely-resistive circuit. For inductive or capacitive circuits, the current either lags or leads the voltage.
series circuits have 1 pathway they have constant current(Amperes) not constant voltage. Resistance=R+R+R+...
