Temperature 79404

The aluminum coil line has a resistance of 4.6 Ohm at an elevated temperature of 64°C. At what base temperature will the resistance be 2 ohms?

Correct answer:

t2 =  -77.3043 °C

Step-by-step explanation:

t1=64 °C R1=4.6 Ω α=0.004 R2=2 Ω  R2 = R1R1 α Δ Δ=α R1R1R2=0.004 4.64.62=233250141.3043 °C  t2=t1Δ=64141.3043=77.3043°C
