Testing & TroubleshootingQuestion 490 of 521
A conductor run carries 10 A and the total round-trip resistance of the wire is 0.5 ohms. What is the voltage drop along the conductors?
a.20 V
b.0.05 V
c.10.5 V
d.5 V
Explanation
Voltage drop Vd = I x R = 10 A x 0.5 ohms = 5 V. Option a divides I by R inverted, b divides R by I, and c adds the numbers, none is Ohm's law applied to the wire resistance.
