What is the relation between resistance and power?

The power dissipated in a resistor is given by P = V2/R which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases.

What is the relationship between power current voltage and resistance?

Ohm’s law defines the relationship between the voltage, current, and resistance in an electric circuit: i = v/r. The current is directly proportional to the voltage and inversely proportional to the resistance.

What is the relationship between power potential difference and resistance of a conductor?

The relationship between Potential Difference, Resistance, and Current is given by Ohm’s Law, which states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the “resistance”, R.

Is power independent of resistance?

Resistance is a constant of proportionality. It doesnot depend on power. Whichever equation used the variable quantities are voltage and current only. Resistance is independent from power.

Is power inversely or directly proportional to resistance?

From here, we can see that the power P is inversely proportional to the resistance R. When the power in the circuit is high, resistance will be lesser. However, if the power is low, the resistance will be high.

What is the relation between resistance and resistivity?

Relation between Resistivity and Resistance is: R=ρlA, where ρ is the resistivity, l is the length of the conductor and A is the cross sectional area. We know that the resistivity of a material depends on the temperature.

Is power directly proportional to resistance or inversely proportional to resistance?

How power is directly and inversely proportional to resistance?

If you assume I is constant and replace V with IR, you get that power is proportional to resistance (P=I⋅(IR)). If you assume V is constant and replace I with VR, you get that power is inversely proportional to resistance (P=V⋅VR).

What is the difference between resistance and resistivity also derive the relation between resistance and resistivity?

Resistivity is only proportional to the nature and temperature of the particular material. The SI unit of resistivity is Ohms-meter….Resistivity.
