21 R 1 The formula to calculate the demand for power P is given by P= d² power increases by more than 9%, load shedding is implemented. If the demand for .1.1 On a cold winter's night, the current I changes by ±3%, the resistance R changes by ±2% and the cable diameter d changes by ±2%. Calculate the maximum change in power. Will load shedding be implemented? Give a reason for your answer. .1.2
