A certain resistor has a color code of Red/Red/Red/Gold). If this resistor were connected across the terminals of a 12 volt car battery, what nominal current would flow through the resistor?

Question

Quizplus · Accepted Answer

The resistor's color code of Red/Red/Red/Gold translates to a resistance value of 2.2kΩ (2200Ω) with a tolerance of ±5%. Using Ohm's law (I = V/R), the current I = 12V / 2200Ω = 0.00545A or 5.45mA.
