Examples: CR CR Diode 1. r = more than 20 to 30 ohms 2. In an AC circuit impedance of L is to be somewhat smaller than impedance of r and c. Can be used for both AC and DC circuits. Use 500 to 1000 ohms for r and 0.1 µF to 0.2 µF 200 V for c in a general 12 to 24 V load circuit. For DC circuits only. S Relay contact : Inductive load rc L L r S c L S L |
