Question: Electrical power P is given by where E is voltage and R is resistance. Approximate the maximum percent error in calculating power when 120 volts

Electrical power P is given by

P = E2 R

where E is voltage and R is resistance. Approximate the maximum percent error in calculating power when 120 volts is applied to a 2000-ohm resistor and the possible percent errors in measuring E and R are 3% and 4%, respectively.
