Question
The power P (watts) in an electric circuit is related to the circuit's
resistance R (ohms) and the current I (amperes) by the equation P = R 1².
Use differentials to determine by approximately how many watts the power
changes if the current changed from 5 amperes to 5.1 amperes and the resistance
changed from 4 ohms to 3.6 ohms due to error in measurements.
Enter your answer without units.
Enter an integer or a fully reduced fraction such as -2, 7, -3/4, 41/7 etc.
