A3.80 mm diameter wire carries a 15.2 A current when the electric field is 8.60×10-2 V/m Part A What is the wire's resistivity? p= 6.42×10-8 m Submit Previous Answers ✓ Correct Correct answer is shown. Your answer 6.4167-10-8 = 6.4167x10-8 m was either rounded differently or used a different number of significant figures than required for this part. ▼ Part B If a battery voltage of 8.55 V is applied to this wire to produce this current, how long must it be?
