1. [-/2 Points] DETAILS A circuit breaker is rated for a current of 50 A rms at a voltage of 110 V rms. (a) What is the largest value of I max that the breaker can carry? (b) What average power can be supplied by this circuit? KW2. [43 Points] DETAILS The capacitor in the figure below is designed to filter |ov.n.I-frea:|uenc',.r signals, impeding their transmission between circuits. Circuit {a} What capacitance is needed to produce a 1?.5 kn reactance at a frequency of 222 Hz? :nF (b) What would its reactance be at 1.00 MHz?I S n (c) What are the implications of your answers to {a} and {b}? (Select all that apply.) l:l Low frequencies transmit better than high ones. D The capacitor does not do What it is designed to do. l:l Reactance is larger at high frequencies. l:l Reactance is smaller at high frequencies. B High frequencies transmit better than low ones. D The capacitor does what it is designed to do. 3. [-3 Points] DETAILS For the circuit shown below, what are the following? (120 V)sin(1201rt) 7.0 o 410 pF 35 mH (a) the total impedance [in Q) :0 {b} the phase angle between the current and the emf (in rad) (c) Write an expression for Kt}. (Use the following as necessary: it. Assume J'(f) is in amps and t is in seconds. Do not include units in your answer.) :13) = 4. [-/2 Points] DETAILS (a) Calculate the resonant angular frequency (in rad/s) of an RLC series circuit for which R = 23 0, L = 84 mH, and C = 4.6 JF. rad/s (b) If R is changed to 300 0, what happens to the resonant angular frequency? O The resonant angular frequency would increase. O The resonant angular frequency would decrease. O The resonant angular frequency would remain the same.5. [-5 Points] DETAILS | MY NOTES (a) What is the voltage output of a transformer used for rechargeable flashlight batteries if its primaryr has 47? turns, its secondary has 8 turns, and the input voltage is 110 V? |:|V (b) What input current is required to produce a 4.00 A output? Em (c) What is the power input? |:|W
