You apply the rule to each loop in the circuit individually, and each loop produces
a separate equation. You solve the collection of equations for the individual loop
currents.

How the diameter of conductor can be calculated for a perticular voltage?
It's not the voltage that determine the size of the conductor,it's the current. The rule of thumb is: 6A for every 1mm sq
What is the advantages of using voltage divider rule in series resistive network?
You get proportional (equal) amp pressure throughout.
State Kirchoffs voltage and current law?
Kirchoffs Current Law : [KCL]This law is also called Kirchhoff's point rule, Kirchhoff's junction rule (or nodal rule), and Kirchhoff's first rule. The principle of conservation of electric charge implies that: : At any point in an electrical circuit that does not represent a capacitor plate, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point. Kirchoffs Voltage Law : [KVL]This law is also called Kirchhoff's second law, Kirchhoff's loop (or mesh) rule, and Kirchhoff's second rule. : The directed sum of the electrical potential differences around any closed circuit must be zero.Kirchoffs Laws are widely used in the Electrical and Electronic engineering fields.Hope this helps =)
How to reduce voltage drop during long transmission of power?
You reduce voltage drop by increasing conductor size. As a general rule, if you believe you have a voltage drop problem, install the next size larger conductor.Voltage drop can be calculated using the formula E=IR, where I is the anticipated current required by the load, R is the resistance of the conductor, and E is voltage, or in this case is voltage drop. If the answer for E is more than 3% of the circuit voltage or 5% of the service voltage, you need to increase conductor size.AnswerBy increasing the supply voltage of the transmission line. This is why very high voltages are used in electrical transmission systems.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How would you connect a resistor in order to reduce an LED's applied voltage?
You could use the voltage divider rule to reduce the voltage. Using two resistors in series, the input voltage will drop across each resistor by an amount that is proportionate to the values of the resistors. If the 1st resistor is 10K and the 2nd resistor is 100K, the voltage drop across the 10K will be 10 times LESS than that of the 100K resistor. The total voltage drop across both resistors will be equal to the supplied input voltage. Work out the ratio of voltage you need from the total input voltage and use 2 resistors will that give you the same ratio. Connect the LEDs in parallel with the resistor the gives you the voltage you want. Use a MM to measure the voltage across the resistor before wiring LEDs.
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.
Is a fan a complex machine?
There's a rule of thumb when it comes to complex machines. If it can't be made with LEGO's, it's complex.

How can you increase voltage of an ac adapter?
Increase primary voltage but decraease amerage - eg double voltage and half amperage. This will double your secondary voltage. "Transformed" voltage is easy to understand by following this simple math rule. secondary voltage divided by primary voltage = no of turns on secondary and no of turns on primary. eg; 240v \ 12v = 20 (factor) this means the secondary winding is 20x the primary winding. Basically thats all I know Stick to this rule for step up & step down tranforming & you'll be sweet.
Can you use adapter with output 5v 3amp to operate adevice with 5v 1amp?
Absolutely. The first rule: Source voltage should be equal to the device voltage. The second rule: Source current sould be higher than the cumulative of the device's current.
What is NEC 210-4B?
It is a electrical code rule taken from the National Electrical Code book. It has to do with multi wire branch circuits.
Does copper need a voltage to produce a current?
Copper can not of itself produce a current. <><><><><> However, resistance, be it copper or some other material, will produce a current if a voltage is applied to it. The rule is Ohm's law: Current = Voltage divided by resistance.
Rothschild's rule states for a complex problem?
“For every phenomenon, however complex, someone will eventually come up with a simple and elegant theory. This theory will be wrong.”
Is there a rule to distance of cable from a power source to low voltage lighting without voltage drop and do you have to put transformers or outlets in the yard?
Voltage drop depends on the size & length of the wire and the wattage of the bulbs. If they make an LED replacement bulb , you would hardly notice the voltage drop.
What is the name of the law that states that a more complex system cannot be created in a less complex one?
Occum's Rasor. This isn't a law, just a highly respect rule.
What is the rule for voltage across each resistor?
Volt across a resistor = resistance x current through the resistor.
What is the advantages of using voltage divider rule in series resistive network?
You get proportional (equal) amp pressure throughout.
