The Power in Watts for a Circuit Is Given by P

question 114

Short Answer

The power in watts for a circuit is given by P = I ²R. How fast is the power changing if the resistance, R, of the circuit is 900 $\Omega$ , the current, I, is 7.7A, and the current is decreasing with respect to time at a rate of 0.025 A/s? (Assume the resistance is constant.)
