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.
