Consider a series RLC circuit with a resistor R = 51.0 Ω, an inductor L = 2.20 mH, a capacitor C = 0.0722 µF, and an AC source that provides 0.155 volts RMS at 25.8 kHz (kilohertz). What is the impedance (ohms) of the circuit? (State answer as a whole number with no decimal).

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
