Resistor Applications Resistors are used for: Limiting current in electric circuits. Lowering voltage levels in electric circuits (using voltage divider). As current provider. As a sensor (e.g., photoresistor detects light condition, thermistor detects temperature condition, strain gauge detects load condition, etc.) In electronic circuits, resistors are used as pull-up and pull-down elements to avoid floating signal levels.

Resistors: Power Rating and Composition It is very important to be aware of power rating of resistor used in circuits and to make sure that this limit is not violated. A higher power rating resistor can dissipate more energy that a lower power rating resistor. Resistors can be made of: Carbon film (decomposition of carbon film on a ceramic core). Carbon composition (carbon powder and glue-like binder). Metal oxide (ceramic core coated with metal oxide). Precision metal film. High power wire wound.

Resistor Labels Wire-wound resistors have a label indicating resistance and power ratings. A majority of resistors have color bars to indicate their resistance magnitude. There are usually 4 to 6 bands of color on a resistor. As shown in the figure below, the right most color bar indicates the resistor reliability, however, some resistor use this bar to indicate the tolerance. The color bar immediately left to the tolerance bar (C), indicates the multipliers (in tens). To the left of the multiplier bar are the digits, starting from the last digit to the first digit.

Слайд 37


Capacitor Construction A capacitor is constructed using a pair of parallel conducting plates separated by an insulating material (dielectric). When the two plates of a capacitor are connected to a voltage source as shown, charges are displaced from one side of the capacitor to the other side, thereby establishing an electric field. The charges continue to be displaced in this manner until the potential difference across the two plates is equal to the potential of voltage source.
