What is the relationship between power and resistance?

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.

Why power is directly and inversely proportional to resistance?

power is inversly proportional to resistance as power is the rate of flow of electrical energy through a conductor with potential diff n more energy is used for more resistance.

What is inversely proportional to electric power?

As per the power formula, if the power stays the same then current is inversely proportional to the voltage.

What is directly proportional to resistance?

As value of resistance(R) is directly proportional to length of resistance, so by increasing the length of resistance the value of resistance increases. Resistance also depends on the material of the conductor.

Does resistance increase with power?

When power increases, the resistance will also increase keeping current I constant. When Resistance decreases, Power also reduces keeping current I constant.

Is resistance a form of power?

In these statements the distinct identities of’power’ and ‘resistance’ are not lost. But as ‘resistance’ is presented as a function of’power’ the two concepts exist in tandem rather than as separate aspects ofthe concept ‘power relation’.

Is resistance directly proportional to voltage?

The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.

Are resistance and resistivity inversely proportional?

Resistance is proportional to resistivity and length, and inversely proportional to cross sectional area.

Which variable is inversely proportional to the resistance?

Current
Current is inversely proportional to the resistance. A threefold increase in the resistance would cause a threefold decrease in the current. 5.
