A device is measuring the voltage drop across an electric heating element. This device is an ohmmeter as a nominal resistance of 30? and a power rating of 1800W . Availa (accuracy: within 1.0%; resolution: 0.8?) and ammeter (accuracy: within 0.1% resolution: 200mA). Recall E-IR and P-EL a) (5 points) What is the instrument uncertainty of ammeter? b) (5 points) What is the design-stage uncertainty of ohmmeter? c) (10 points) Estimate the design-stage uncertainty in determining the voltage dr the voltlage drop E
