- Remember: Resistance is measured on Ohms (Ω)
- Resistors obey Ohm’s Law, V = IR
- – as applied voltage increases, current through the resistor increases proportionately
- Resistors dissipate power as heat
- (P = I2R = V2 ÷ R)
- Resistors have specific rated power dissipation
- – 0.25W, 0.5W, 1W, 2W, 5W ...
- If exceeded component may fail!
