Using the schematic of the circuit, calculate the total resistance of the circuit. req = 35 incorrect: your answer is incorrect. ω based on the calculated resistance and the voltage across a and b ("voltage, a - b" above), calculate the theoretical value of the current using ohm's law. icalculated = 0.0407 incorrect: your answer is incorrect. a calculate the percent error between the calculated current and the measured current. % error = calculated − measured calculated × 100% = %
