An extension cord has a resistance of 0.0600 ohm and carries 5.00 A to a power tool. What is the voltage drop along the cord?

1. The voltage drop along a conductor is its IR drop: V = IR. 2. Substitute: V = 5.00 A x 0.0600 ohm. 3. Multiply: V = 0.300 V. 4. That drop is lost to the cord, so the appliance sees slightly less than the outlet voltage. 5. 0.833 V is the trap of dividing the current by the resistance's leading digit instead of multiplying I by R. _Source: OpenStax College Physics (CC BY 4.0), Ch 20 "Electric Current, Resistance, and Ohm's Law", section 20.2 Ohm's Law: Resistance and Simple Circuits_
