Estimate the design-stage uncertainty in determining the voltage drop across an electric heating element. The device has a nominal resistance of 30 ? and power rating of 500 W. Available is an ohm meter (accuracy: within 0.5%; resolution: 1 ?) and ammeter (accuracy: within 0.1 % ; resolution: 100 mA). Recall E IR Hint: E- IR or in terms of power, P-PR
