An ammeter reads 0.2 A with an internal resistance of 0.1 Ω. In a circuit with 60 Ω external resistance, find the true current and the impact of the internal resistance on measurement accuracy.
💡 Hint: Calculate for how the internal resistance influences results.
You measured 12.5 V across a resistor with a 5 V power supply and a voltmeter with an uncertain reading of ±0.5 V. Discuss how to account for total measurement uncertainty.
💡 Hint: Think about combining both power and voltmeter uncertainties.
