Does Kirchhoff current law and Kirchhoff voltage law depend on the relationship between current and voltage in a resistor?
Kirchhoff's Voltage and Current Laws apply to circuits: series, parallel, series-parallel, and complex.
If your circuit comprises just a single resistor, then they still apply. For example, the voltage drop across a single resistor will be equal and opposite the applied voltage (Kirchhoff's Voltage Law), and the current entering the resistor will be equal to the current leaving it (Kirchhoff's Current Law).

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 =)
A can be used to reduce the current in a circuit?
A resistor.
What happens when resistance is varied in a circuit?
A resistor will not change its value, unless the voltage exceeds the designed power capacity of the resistor. As the voltage increases, the current will increase, if the current gets too high it will cause the temperature of the resistor to increase, if the temperature exceeds the power rating of the resistor then the resistance WILL change. If it goes too High in temperature the resistor will open and current will no longer flow. A resistor is used to control current, and indirectly the .voltage depending on the application. Hope This helps. You must use Ohms Law to see the relationship.

What can be said about the relationship between voltage and current provided that the resistance is fixed?
It's linear and direct, up to the current-carrying capacity of the resistor.
What is the relationship between resistors connected in series and the flow of current through them?
When resistors are connected in series, the flow of current through them is the same. This means that the current passing through each resistor is equal, as it has to pass through each resistor in the series circuit.
The nodal analysis is primarily based on the application of?
Nodal Analysis is primarily based on the application of Kirchhoff's Laws. Nodal Analysis uses Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL) (and even Ohm's Law) to determine the voltage and current between each node of an electric circuit.
What law expresses the relationship between the current in a resistor and the rate at which it produces heat?
.Faraday's Law Joule's Law Lenz's Law Ohm's Law
What is the phase difference between the current through the resistor and inductor in an AC circuit?
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
How do you measure current and voltage in circuit by kirchoff's method?
Kirchhoff (not 'Kirchoff') doesn't suggest any way of measuring current or voltage in a circuit. Kirchhoff's Voltage Law defines the relationships between potential differences around any closed loop within a circuit. Kirchhoff's Current Law defines the relationships between currents at any junction within a circuit. Kirchhoff's Laws may also be used to solve complex circuits ('complex' circuits are those circuits which are not series, parallel, or series-parallel). Current and voltage may be measured with an ammeter and a voltmeter, respectively.
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
How does current change across a resistor?
Current changes across a resistor in direct proportion to the voltage applied. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I V/R.
What kind of relationship can be concluded about the voltage difference across a resistor and the current flowing through it?
POWER=VI. V=voltage I= current
How does current change through a resistor?
When an electric current flows through a resistor, the resistor resists the flow of the current, causing a decrease in the current. This decrease in current is proportional to the resistance of the resistor, as described by Ohm's Law.
What is the relationship of current through the resistor and inductor in the LR parallel circuit?
When they are in parallel the same voltage appear across both. The resistor carries a current of V/R, the inductor carries a current of V/(jwL). So the current in the inductor is 90 degrees behind in its phase.
