QUESTION:

The equation \(P=V^{2}/R\) indicates that the power dissipated in a resistor decreases if the resistance is increased, whereas the equation \(P=I^{2}R\) implies the opposite. Is there a contradiction here? Explain.

ANSWER:

Step-by-step solution

Step 1 of 2

The power equation:

This equation shows a decrease in power when resistance increases, and implies that the voltage is constant.

The power equation:

When resistance increases we get increase of power and the current is constant.
