Three Colors for a 10 ohm resistor Answer - Brown Black Brown Three Colors for 4.7 ohm resistor Answer - Yellow Violet Gold Two Terminal current control circuit device Answer - rheostat 12 Volt battery across red red red resistor, mW dissipated by resistor Answer - .65.5 mW Resistance Equivalency formula Answer - R1 x R2/R1+R2 The larger the capacitor, the smaller/larger the voltage drop Answer - smaller Most common use of capacitors is to store ___________ Answer - energy When plates of a series -resonant tuning circuit are moved closer together, the resonant frequency of the turned circuit increase/decrease Answer - decrease. Moving plates closer together increases capacitance which decreases the resonant frequency fc= 1/2π√LC True or False, the purpose of a 0.01 µF capacitor in parallel with a filter capacitor is to increase the capacitance Answer - False, it is to offer a low reactance path to high frequency transients A 0.05 µF capacitor is connected in series with a 0.08 µF capacitor. The series circuit has a capacitance of Answer - .05x.08/.05+.08 µF = .031 µF Inductors store energy in the form of a ___________ field Answer - electromagnetic field To prevent electrostatic coupling between the primary and secondary windings, power transformers are sometimes equipped with a ____________ shield Answer - Faraday shield The dot notation on a transformer tells which points are (in phase)(equal to current) Answer - in phase Name two types of transformers that can be used as preregulators Answer - ferroresonant and self saturating.
