1.Resistance is dependent on the material.Like wood is insulator(ALMOST infinite resistance).
2.Resistance of a wire having more cross sectional area is less and less cross sectional area is more(i.e. it is inversely propotional to the cross sectional area.)
3.It is more for more length and less for less length.
4. Resistance varies with temprature.For metals like platinum it increses with temprature.

What is the relationship between capacitor resistance and the overall performance of an electronic circuit?
The relationship between capacitor resistance and the overall performance of an electronic circuit is that the resistance of a capacitor affects the charging and discharging times of the capacitor, which can impact the timing and stability of the circuit. Higher resistance can lead to slower charging and discharging, potentially affecting the circuit's functionality and efficiency.
What is the role of resistance in an electric circuit and how does it affect the flow of current?
Resistance in an electric circuit is the opposition to the flow of electric current. It is measured in ohms. Resistance affects the flow of current by reducing it, as higher resistance leads to lower current flow. This relationship is described by Ohm's Law, which states that current is inversely proportional to resistance in a circuit.
What causes resistance in a circuit and how does it affect the flow of electricity?
Resistance in a circuit is caused by factors like the material of the wires and components, temperature, and length of the circuit. It affects the flow of electricity by slowing it down and converting some of the electrical energy into heat. This can lead to a decrease in the overall current and voltage in the circuit.
Resistance is a energy?
Resistance is not energy; it is a property that opposes the flow of electric current in a circuit, leading to the dissipation of electrical energy in the form of heat. Energy is the capacity to do work or produce heat, and resistance is one factor that affects the amount of energy that is dissipated in a circuit.

How does resistance affects electric current?
Ohm's law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of a circuit.

Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
Does a volt meter takes power from the system?
No it does not. A volt meter only reads the current that is passing through it.AnswerAll instruments draw some (albeit tiny) current from the circuit under test in order to operate. So, if this is what you mean by 'taking power from circuit', then the answer is yes, it does.Instruments also change the normal resistance of the circuit being tested -for example, ammeters increase the resistance of the circuit into which they are connected, while voltmeters decrease the circuit resistance across which they are connected. So adding a voltmeter (or an ammeter) to a circuit affects the operation of that circuit to some degree. To minimise this interference, it is important that an ammeter's internal resistance is very much lower than the circuit's resistance, and a voltmeter's resistance is very much higher than the circuit's resistance.

What is the relationship between resistance and capacitance in a circuit with a capacitor, and how does the resistance affect the charging and discharging process of the capacitor?
In a circuit with a capacitor, resistance and capacitance are related in how they affect the charging and discharging process of the capacitor. Resistance limits the flow of current in the circuit, which affects how quickly the capacitor charges and discharges. Higher resistance slows down the charging and discharging process, while lower resistance speeds it up. Capacitance, on the other hand, determines how much charge the capacitor can store. Together, resistance and capacitance impact the overall behavior of the circuit with a capacitor.
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
How is the total resistance in a series circuit is determined?
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
