A student builds a circuit with a DC power supply, a resistor, and an ammeter to measure current. The resistor is labeled 82.0 Ω (±5%). The student applies different voltages and records the current: Voltage (V) Measured Current (A) 3.0 0.036 6.0 0.073 9.0 0.110 12.0 0.146 (a) For each trial, calculate the resistance using Ohm’s Law.(b) Determine the average experimental resistance from the data.(c) Compare the average resistance with the nominal 82.0 Ω and comment if it falls within the ±5% tolerance.(d) For the 12.0 V trial, calculate the power dissipated by the resistor.(e) Discuss whether the data supports Ohm’s Law (i.e., current directly proportional to voltage).
