Resistors
Resistors are truly iniquitous.They are almost as many types as thier applications. Resistors are employ in amplifiers as loads for active devices,in bias network,and as feedback elements. in combination with capacitor they establish time constant and act as filters,they are employed for setting operating current and signals levels.They are employed in powerpower circuits to reduce voltage by dissipapower power,to measure current ,and to discharge capacitor after supply is removed.Resistor are employed in precision circuit to establish currents, to provide accurate voltage ratios and to set precise gain values. In logic circuits they act as bus and line terminator and as "pull-up" and "pull-down" resistors,in high-,voltage circuit they are employ for measuring voltage and equalising leakage currents among diodes or capacitor connected in series. In radio frequency (RF) circuit they are even employed as coil forms for inductor
