DC Fundamentals Unit 6 – Ohm's Law
Resistance is a physical property that can be predicted and measured against manufactured
values.
Manufacturers place color bands on the bodies of resistors to indicate their value. These color
bands follow a standard resistor color code, which was discussed in the "Electronic Quantities"
unit.
NEW TERMS AND WORDS
Ohm's law - In any dc electric circuit, the current is directly proportional to the voltage and
inversely proportional to the resistance. In its simplest form, Ohm's law is expressed
mathematically as E = IR (voltage equals current times resistance).
