A classroom two-wire measurement uses a constant test current of 0.15 A. The reference resistor is 0.75 Ω; its two current leads are 0.12 Ω and 0.18 Ω. Measured voltage spans resistor AND both leads. Indicated resistance=measured voltage/current. A separate ideal four-wire sense measures only the voltage across the resistor, drawing zero sense current. Ignore all other errors; this is a supplied circuit model, not a live measurement procedure.
Calculate the ideal four-wire sense voltage in V. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
